14K Yellow Gold Custom Engagement Ring with Elongated Hexagon Lab-Grown Diamond and Floral Pavé Diamond Setting

This custom engagement ring is one of the most detailed pieces we've made, and the photo still doesn't fully do it justice. At the center is a 10.91x5.34mm elongated hexagon lab-grown diamond — a long, narrow cut with pointed tips and a step-cut geometry that throws broad, clean flashes of light rather than scattered sparkle. The elongated hexagon is an unusual shape, and this setting was designed specifically to complement it.

The setting itself is the story here. A floral-inspired split shank opens beneath the center stone into two branching strands of 14K yellow gold, each one lined with a mix of marquise, round, and pavé-set diamond accents. The strands twist and intertwine as they move toward the back of the ring, with organic curves and branches that give the whole structure a botanical quality — less like metalwork and more like something that grew. A single round diamond accent sits at the base of the center stone, tucked into the split where the two shanks divide, adding a point of brilliance right at the heart of the design.

There is a lot happening in this ring, but it holds together because every element is working in the same direction. The marquise diamonds along the shoulders echo the pointed geometry of the center stone. The pavé rounds fill the negative space without creating visual noise. The yellow gold ties the warmth of the setting to the brightness of the diamonds in a way that feels deliberate rather than default.

This ring highlights:

• 10.91x5.34mm elongated hexagon lab-grown diamond center stone
• Floral split shank with intertwining strands and organic branching detail
• Marquise, round, and pavé diamond accents throughout the setting
• Single round diamond accent at the base of the center stone
• 14K yellow gold throughout
• A fully custom, one-of-a-kind engagement ring crafted to order

This is the kind of ring that takes time to absorb. Every angle reveals something new — a curve in the shank, a marquise catching the light, the way the two strands come together at the back. It was made for someone who wanted something genuinely unlike anything else.

If this level of detail and craftsmanship is what you're looking for, we'd love to talk through what a ring like this could look like built around your stone and vision.
