Split Band Marquise Diamond Engagement Ring
Custom Made by C. Blackburn Jewelers
Lab Grown Marquise Diamond Ring
Seen head-on, the marquise diamond’s elongated silhouette creates a dramatic yet graceful presence.
Its crisp, symmetrical facets reflect light in sharp flashes, giving the ring a regal, contemporary elegance.
Set vertically, the stone draws the eye upward along the finger, offering the naturally slimming effect that makes the marquise cut so distinctive and timeless.
Fine Hand Engraving & Milgraining
From the side, the refined craftsmanship of this custom marquise engagement ring comes into focus. The setting is airy and open, allowing light to enter freely beneath the diamond and intensify its fire and brilliance.
Finely proportioned prongs protect the marquise’s pointed tips while maintaining a delicate, elegant profile.
Along the shoulders, subtle hand engraving and crisp milgraining add vintage character and texture, giving the ring a graceful architectural lift as it rises toward the center stone.
The result is a design that feels light, secure, and beautifully balanced from every angle.
Split Shank Custom Engagement Ring
As the band approaches the center stone, it transitions into a beautifully balanced split shank, dividing into slender arms that frame the diamond with subtle architectural detail.
This thoughtful design adds lightness and dimension without distracting from the center stone, allowing the ring to feel both graceful and structurally precise.
The result is a custom engagement ring that blends classic sophistication with the signature handcrafted craftsmanship of C. Blackburn Jewelers in La Jolla, CA.
