Custom-Made Modern Engagement Ring
by San Diego Jewelry Designer Carl Blackburn
Cushion Cut Lab-Grown Diamond
This custom engagement ring by Carl Blackburn takes a distinctly modern approach to elegance, combining bold geometry with soft flowing lines in a way that feels sculptural yet highly wearable. Set in 18K yellow gold, the design creates its character through proportion, negative space, and the relationship between the center stone and its mounting. From this angled front view, the ring immediately feels clean, confident, and quietly dramatic.
At the center of this engagement ring is a 3.62 carat E color, VVS2 clarity Cushion Cut lab-grown diamond whose softened corners give the stone a more fluid and romantic personality than a traditional rectangular shape. The elongated proportions provide impressive finger coverage while maintaining a graceful silhouette. Because of the faceting pattern, the brilliance appears broad and dynamic, with larger flashes of light moving across the surface rather than the tighter sparkle associated with smaller facet structures.
What immediately defines the ring is the bezel setting surrounding the diamond. Instead of prongs outlining the edges, the polished 18K yellow gold frame creates a smooth uninterrupted border around the stone, giving the design a cleaner and more contemporary identity. The bezel also accentuates the elongated shape of the diamond, making the geometry feel even more sculptural and substantial.
Custom Bezel Set Diamond Ring
From the side profile, one particularly elegant detail becomes especially clear. The bezel lifts slightly above the shoulders and separates subtly as it approaches the center stone. That open split introduces a sense of tension and lightness into the structure, preventing the bezel from feeling visually heavy.
The 18K yellow gold contributes significantly to the atmosphere of the ring. Its warmth softens the stronger geometry and keeps the design from becoming cold or overly minimal. Against the bright white brilliance of the diamond, the gold creates rich visual contrast and additional depth. The polished surfaces also help the ring feel fluid rather than rigid, with light moving smoothly across the band and setting.
From this angle especially, the care given to proportion becomes very apparent. The bezel remains substantial enough to feel protective and sculptural while staying thin enough to avoid overwhelming the 3.62 carat center diamond. The band tapers naturally into the setting, allowing the eye to move fluidly toward the stone.

From the rear view, the ring’s sculptural construction becomes even more apparent. The open architectural mounting beneath the stone allows light to move through the diamond while preserving the clean, modern language of the design. The shoulders rise toward the bezel in a graceful split form, creating negative space that gives the ring both visual interest and a sense of lightness.
One of the most successful aspects of this Carl Blackburn ring design is its restraint. There are no halos, accent stones, or decorative flourishes competing for attention. Every line feels purposeful, allowing the focus to remain entirely on shape, structure, and the interaction between metal and light. Despite its modern appearance, the ring also carries a timeless quality.
Bezel-set diamonds have long been valued for their durability and elegance, but this interpretation feels distinctly contemporary because of the elongated proportions, the bright Cushion Cut lab-grown diamond, and the open architectural mounting beneath the stone.
The overall effect is sleek, refined, and quietly dramatic — an 18K yellow gold engagement ring that creates presence through balance, precision, and confident simplicity rather than decorative excess.
