Carl Blackburn Engagement Rings

Gallery of Custom Hand-Crafted Rings in San Diego

This custom-crafted C. Blackburn engagement ring showcases a striking 2-carat marquise-cut diamond at its center — a beautifully elongated gemstone known for its elegant proportions, flattering shape, and exceptional light return.

 

The marquise diamond is set into a sculpted 14K yellow gold mounting, where carefully executed prong work and hand-applied engraving both protect and visually frame the stone, blending strength with refined craftsmanship.

 

The shoulders of the ring are decorated with intricate, fan-inspired engraved motifs, each one accented by small round brilliant diamonds set within delicate milgrain borders.

 

These thoughtful details introduce a gentle sparkle and emphasize the artistry of the design, creating a rich contrast between the bright white accent stones and the warm, glowing tone of the yellow gold.

 

The band itself is shaped with a smooth, softly contoured profile, giving the ring a graceful flow and providing balance to the more ornate engraved elements.

 

This engagement ring is an ideal choice for someone seeking a piece that feels both heirloom-inspired and genuinely distinctive, combining classic elegance with a bold, memorable presence.

Designed by San Diego jeweler Carl Blackburn, this three-stone ring is built around an extraordinary 14.06-carat lab-grown emerald-cut diamond, a cut known for its stepped facets, crisp lines, and bold architectural character.

 

The center stone sits in a bright, platinum-style mounting, held by sculpted claw prongs that raise the diamond and allow light to enter freely from all sides.

 

On either side, tapered baguette diamonds extend the composition with a clean, linear flow.

 

Their elongated proportions and precise geometry reference classic Art Deco design, while the strong symmetry and carefully balanced transitions between the stones give the ring a vintage sensibility without sacrificing a contemporary sense of scale.

 

A smooth, weighty band anchors the design and keeps the focus firmly on the gemstones above.

 

With its blend of Deco influence and modern confidence, this ring is an excellent choice for someone who appreciates structure, craftsmanship, and a piece that commands attention without excess.

Inspired by the refined jewelry traditions of the early twentieth century, this engagement ring by Carl Blackburn is crafted around a 2.52-carat marquise-cut diamond set in rich yellow gold.

 

The elongated center stone is held in place by graceful claw prongs influenced by antique European mountings, which elevate the diamond and give it a luminous, airy presence while preserving a distinctly vintage silhouette.

 

Across the band, hand-cut scrollwork and finely engraved decorative patterns introduce layers of texture and visual interest drawn from Victorian and Edwardian ornament.

 

Every curve, line, and flourish is shaped with intention, contributing to a sense of heritage and creating a piece that feels romantic, substantial, and meant to be passed down.

 

The marriage of the marquise shape — long celebrated for its flattering, lengthening proportions — and the warmth of the gold setting results in a pleasing balance between brilliance and old-world charm.

 

Viewed from any angle, the ring reveals detailed engraving and thoughtful finishing, making this custom design a timeless expression for someone who values classic artistry brought to life through modern craftsmanship.

This Renaissance-inspired engagement and wedding ring set by Carl Blackburn was created as a deeply personal, one-of-a-kind design, blending sculptural artistry with symbolic detail drawn from music, history, and romance.

 

At the center is a luminous oval diamond held in dramatic eagle-claw prongs, a bold and expressive setting choice that evokes the grandeur and confidence of classical European jewelry traditions while giving the stone a commanding, elevated presence.

 

Flowing along the shoulders of the engagement ring are sculpted violin F-hole motifs, integrated seamlessly into the structure of the band and accented with delicate diamond blossoms representing baby’s breath flowers.

 

These elements are not merely decorative, but narrative in purpose—each curve and flourish reflecting Sara’s love of music and the poetic, organic forms found in Renaissance and early classical ornamentation.

 

Fine milgrain beading and hand-engraved details add layers of texture and depth, rewarding closer inspection from every angle.

 

The accompanying wedding band continues this story with matching hand-engraved laurel wreath motifs encircling the ring, a symbol long associated with honor, devotion, and timeless love.

 

The engraving is executed with exceptional precision, giving the band a rich, heirloom character that feels both substantial and delicately refined, while remaining perfectly in harmony with the engagement ring’s sculptural presence.

 

Together, the set forms a unified composition that feels romantic, expressive, and enduring. 

Designed by Carl Blackburn, this platinum engagement ring features a luminous round brilliant diamond set in a refined four-prong mounting, with an elevated profile carefully engineered to draw in light from every direction and intensify the stone’s fire and sparkle.

 

The wide, substantial band is richly decorated with custom-cut French Cut diamonds — a historic cutting style associated with the Art Deco era and valued for its crisp geometry and distinctive, mirror-like flashes.

 

These square stones are precision channel-set, forming continuous, seamless ribbons of brilliance along each side of the ring.

 

Bordering the French Cuts are rows of finely set pavé diamonds that trace the shoulders and continue beneath the gallery, introducing an additional layer of intricate shimmer and visual depth.

 

This thoughtful combination of structured, architectural French Cuts and delicate pavé accents creates a sophisticated dialogue between old-world craftsmanship and modern luxury, balancing strength with elegance.

 

With its confident proportions, meticulous detailing, and couture-level finish, this ring makes a bold yet refined statement — a timeless expression of high jewelry design created for someone who appreciates both drama and precision.

Created by Carl Blackburn, this custom three-stone engagement ring brings together clean modern lines with a distinctly bold, design-forward character.

 

At the center is a natural dark gray emerald-cut diamond, whose deep, smoky tone and crisp step facets give the ring a confident, contemporary presence.

 

Set in bright white metal, the elongated stone is lifted in an open, airy prong structure that allows light to enter freely and emphasizes the diamond’s strong, architectural form.

 

On either side, precisely cut kite-shaped diamonds introduce a striking geometric accent. This unexpected choice subtly references Art Deco influences while aligning perfectly with modern tastes for sharp, sculptural silhouettes.

 

Their bright, icy brilliance plays against the darker center stone, creating a dramatic contrast that feels intentional, balanced, and visually compelling.

 

A slim, high-polish band grounds the design with quiet refinement and keeps the focus on the composition above.

 

The result is a ring that feels both artistic and enduring — a distinctive expression of individuality crafted with timeless attention to detail.

San Diego's Bridal Jeweler

"Carl is simply the finest jeweler in Southern California. I called him in a frenzy a few months before my proposal. I had just received some disappointing renders from a different jeweler regarding the design I had created for my partner’s engagement ring. I was in search of someone who could really create and honor a vintage design. Immediately, I was blown away by Carl’s knowledge, expertise, and confidence in being able to deliver exactly what I wanted to create." - Sam B.

This custom bridal set by San Diego jeweler Carl Blackburn brings together a romantic morganite engagement ring and a beautifully coordinated diamond wedding band, creating a unified design that blends soft color with luminous sparkle.

 

At the heart of the engagement ring sits a pear-shaped morganite, whose gentle blush-pink tone gives the piece a warm, feminine glow and an immediately inviting presence.

 

Surrounding the center stone is a carefully composed arrangement of round and pear-shaped diamonds that trace graceful, flowing curves around the gem, adding dimension, movement, and layers of light-catching brilliance.

 

The rose gold setting enhances the natural warmth of the morganite and contributes to the ring’s refined, modern elegance while maintaining a soft, romantic character.

 

The matching wedding band is designed to follow the same flowing silhouette, allowing the two rings to nest together seamlessly when worn as a set. Crafted with careful attention to proportion and balance, the band features diamond accents that echo and complement the engagement ring without competing with it.

 

Together, the two rings form a bridal ensemble that brings color, sparkle, and sculptural design into a harmonious and beautifully balanced whole.

This custom engagement ring reflects Carl Blackburn’s distinctive vision for fluid, sculptural form brought to life through meticulous craftsmanship.

 

Shaped in rich 18k yellow gold, the design centers on a perfectly balanced 1.25-carat oval diamond, set within a smooth, bezel-style mounting that feels at once modern in spirit and enduring in character.

 

Instead of using traditional prongs or sharp architectural lines, the diamond is gently cradled by the gold, allowing the metal to move naturally around the stone. This approach emphasizes the oval’s elegant proportions and lively brilliance while also conveying a quiet sense of strength and continuity.

 

The bezel setting provides excellent protection for the diamond, making the ring well suited for everyday wear without sacrificing refinement.

 

The band is subtly contoured and intentionally asymmetrical, with soft, flowing curves that give the piece a distinctly sculpted, hand-shaped presence. When viewed from the side and from behind, the setting reveals carefully considered negative space beneath the diamond, adding lightness and visual interest to an otherwise solid, serene form.

This custom engagement ring by La Jolla jeweler Carl Blackburn is built around a radiant yellow cushion-cut diamond, whose rich color and lively brilliance give the design a warm, expressive presence.

 

On either side, white pear-shaped diamonds frame the center stone, forming a classic three-stone composition traditionally associated with a couple’s past, present, and future.

 

The ring is crafted in yellow gold, a choice that intensifies the golden hue of the center diamond and brings a sense of visual unity to the entire piece. The cushion-cut stone is secured by four sets of double prongs, providing both strength and a subtle nod to vintage-inspired detailing.

 

Viewed from the side, the open gallery reveals elegant curves and finely shaped metalwork that allow light to pass freely through the diamond, enhancing its brightness and fire. A slender, softly rounded band finishes the design with quiet sophistication, keeping the overall look balanced and refined.

 

In the end, this ring blends the enduring beauty of a three-stone setting with the distinctive character and warmth of a fancy yellow diamond, creating a piece that feels both classic and confidently unique.

Designed by San Diego bridal jeweler Carl Blackburn, this custom engagement ring is built around a 3.02-carat antique cushion-cut diamond set in softly glowing rose gold, a pairing that captures the warmth and romance associated with early twentieth-century fine jewelry.

 

The gentle color of the gold enhances the diamond’s character and gives the piece a refined, luminous presence.

 

The mounting is conceived in a vintage style, with sculptural prongs shaped like unfolding petals that rise organically around the center stone. This floral influence echoes the decorative language of Edwardian and early Art Deco solitaires, while the shoulders taper gracefully into a polished band, creating a subtle visual lift that guides the eye toward the diamond’s broad, open facets and distinctive old-world sparkle.

 

Careful contouring along the gallery introduces a hint of architectural interest without drawing attention away from the center stone, striking a thoughtful balance between structure and softness.

 

Finished by hand with meticulous attention to detail, the ring carries a true heirloom quality and is ideally suited for someone who appreciates antique-inspired design interpreted through modern custom craftsmanship.

This blue diamond engagement ring embodies Carl Blackburn’s thoughtful approach to proportion, color harmony, and enduring design.

 

Crafted in bright, luminous white gold, the piece is centered on a striking 1.7-carat fancy blue lab-grown diamond, whose vivid hue brings a sense of individuality and modern romance to a timeless, elegant silhouette.

 

The center diamond’s rich blue tone is both bold and refined, shifting subtly as it catches the light to reveal depth, dimension, and lively brilliance from every angle.

 

Set in a classic prong mounting, the stone is elevated just enough to allow light to enter freely, enhancing its sparkle while keeping the overall profile graceful, balanced, and comfortable for everyday wear.

 

Along the shoulders of the band, white diamonds are arranged in a gentle taper, introducing brightness and a crisp visual contrast. These accent stones frame the blue center diamond beautifully, guiding the eye naturally toward its vibrant color and adding an extra layer of elegance and visual interest without ever overpowering the main stone.

This custom wedding ring set by Carl Blackburn is built around a 2.01-carat pear-shaped rose-cut diamond, selected for its light, translucent character and old-world romance.

 

Unlike modern brilliant cuts, the rose cut’s gently faceted dome produces a soft, glowing shimmer rather than sharp flashes of light, giving the center stone an airy, almost painterly presence.

 

Encircling the diamond is a graceful arrangement of round and marquise-shaped accents, composed in a crown-like formation that adds height, dimension, and refined sparkle while emphasizing the elegant outline of the pear shape.

 

The bands curve smoothly around the finger, each adorned with pavé-set diamonds that contribute a delicate, continuous radiance to the overall profile.

 

Finished in polished precious metal, the set brings together antique-inspired character and modern sophistication. The layered construction allows the engagement ring and wedding band to fit together seamlessly, forming a unified, balanced design that feels cohesive and beautiful from every angle.

Custom Ring Design

"From my very first visit, Carl completely understood my vision. We collaborated to design a custom solitaire that is both deeply personal and breathtakingly beautiful: a Soviet-era inspired setting in rose gold, featuring an old mine cut diamond. The design was based on a beloved ring my grandmother gave me for my 21st birthday, and Carl honored its spirit while creating something totally unique." - Rob W.

This bespoke Art Deco–inspired engagement ring designed by Carl Blackburn captures the era’s fascination with symmetry, contrast, and strong architectural form.

 

At its center are two striking stones—an emerald-cut green emerald and an Asscher-cut diamond—paired to highlight both color and geometry in a distinctly Deco composition.

 

Set side by side in a refined 14k yellow gold bezel-style mounting, the gemstones reflect the crisp angles and structured balance that defined jewelry design of the 1920s.

 

The emerald’s saturated green brings warmth and visual drama, while the Asscher-cut diamond introduces a precise, mirror-like brilliance that feels orderly, elegant, and timeless.

 

The setting itself is smooth and sculptural, with gently tapering lines that follow the contour of the finger for a confident yet comfortable fit.

 

Free from excess ornamentation, the design allows the stones to take center stage, drawing attention to the relationship between shape, color, and light.

 

The result is a ring that feels both contemporary and deeply rooted in Art Deco tradition — clean, intentional, and unmistakably refined. Discover this and other custom designs at C. Blackburn Jewelers in La Jolla, San Diego.

This custom vine-inspired wedding ring by Carl Blackburn in La Jolla showcases a refined balance between natural imagery and precise craftsmanship.

 

Crafted in white gold, the design is anchored by a natural fancy brown diamond—often described as a “rootbeer” diamond—whose warm, nuanced tone brings richness and character to the composition.

 

Surrounding it is a flowing sequence of marquise- and round-cut diamond stations, each individually set and finished with fine hand-applied milgrain detailing.

 

The arrangement of the diamond stations evokes the graceful rhythm of leaves along a vine, giving the ring an organic continuity that appears to gently wrap around the finger.

 

The earthy warmth of the center stone provides contrast against the crisp brilliance of the white diamonds, creating depth while keeping the overall look light and balanced.

 

Beneath the surface, softly scalloped interior openings are thoughtfully incorporated to improve comfort and allow light to move freely through the setting.

 

By pairing botanical inspiration with the clean lines of bezel-style settings, this ring feels sculptural without excess ornamentation.

Carefully shaped claw prongs secure the diamond while subtly highlighting its distinctive geometry. Their open structure allows the stone’s dark luster to stand out, creating a compelling contrast against the bright metal setting and enhancing the ring’s sculptural profile.

Known for its brilliance and purity, the stone’s elongated form creates a bold visual statement while maintaining a refined, graceful presence on the hand.

 

Oriented vertically, the marquise diamond is held by carefully balanced prongs that safeguard its pointed ends without interrupting the flow of light.

 

The open structure of the setting allows illumination to enter freely, intensifying the diamond’s fire and sparkle while showcasing the clean symmetry of its faceting.

 

The marquise cut’s naturally lengthening profile enhances the finger, giving the ring a look that feels both regal and modern.

 

As the band moves toward the center stone, it gently divides into a split shank, forming two slim arms on each side.

 

This transition lightens the visual weight of the ring and adds a sense of airiness and movement, ensuring the design feels elegant, comfortable, and thoughtfully composed from every angle.

This custom engagement ring by Carl Blackburn reflects a thoughtful blend of contemporary design and enduring sophistication.

 

Crafted with precision, the ring features a 1.5-carat lab-grown diamond held within a sleek, full bezel setting.

 

The smooth, sculpted metal surrounds the stone with clean lines, offering a modern aesthetic while still allowing light to interact beautifully with the diamond.

 

Beyond its visual appeal, the bezel provides added security by protecting the diamond’s outer edges.

 

The ring is intentionally designed with a low-profile form, positioning the center diamond close to the finger for a streamlined, comfortable fit.

 

This reduced height helps minimize snagging during daily wear, making the design especially practical for someone with an active lifestyle who values both elegance and ease of wear.

 

Along the shoulders, a series of carefully graduated accent diamonds adds subtle brilliance and depth.

 

These side stones taper outward from the center, enhancing sparkle and dimension without competing for attention, ensuring the main diamond remains the clear focal point of the design.

This elegant engagement ring embodies Carl Blackburn’s belief that truly exceptional diamonds are best showcased through restraint and precision.

 

Crafted in radiant 14k white gold, the design highlights a remarkable 2.02 carat pear-shaped diamond graded D color with VVS1 clarity. The overall effect is clean and sophisticated, resulting in a ring that feels contemporary while remaining enduringly timeless.

 

Set in a vertical orientation, the pear-shaped diamond blends the lively brilliance associated with round cuts and the graceful taper of marquise forms. Its elongated profile creates a natural lengthening effect on the finger, while the stone’s shifting sparkle brings energy and movement to the design.

 

The diamond’s top-tier D color delivers a crisp, icy appearance, and its VVS1 clarity allows light to pass effortlessly through the stone, maximizing fire and scintillation.

 

A refined prong setting holds the diamond securely, offering protection to the delicate pointed tip without adding visual weight. This carefully considered approach keeps the profile airy and balanced, allowing the beauty of the stone to remain the clear focal point of the ring.

One-of-a-kind Custom Rings

"I didn’t know anything about jewelry and was pretty nervous when we started out, but Carl was super helpful, friendly and patient.

Most importantly, my fiancé loves the ring (“It’s perfect.”) and gets so many compliments. Having a one-of-a-kind engagement ring is a really special feeling. I’m so happy I worked with Carl instead of a big chain jeweler." - D. Kearney

Design Your Dream Engagement ring

"Carl is very friendly and excellent at responding to emails and keeping the customer in the loop. Most importantly, he treats every client with respect, no matter what your price point is. During the design process, Carl would listen to my ideas and helped guide me in the right direction. I was able to examine a 3D CAD model of the ring followed by a 3D printed one-to-one scale of the ring. Being able to see both a visual and physical representation of the ring prior to casting it in metal really gave me confidence in the design." - Michael S.
