14K White Gold Custom Engagement Ring with Hexagon Moss Agate Center and Diamond Halo

This custom engagement ring centers on a hexagon-cut moss agate, and no two moss agates are alike. The stone in this ring carries the characteristic dendritic inclusions the gem is known for — dark, branch-like formations suspended inside translucent grey-green clarity, giving the appearance of something living preserved inside glass. It's a stone that rewards a closer look.

The hexagon cut suits it perfectly. Where a round or oval would soften the stone's character, the six straight edges give it structure and geometry, framing the natural patterning inside like a window. A full diamond halo traces the perimeter of the hexagon, following its angular shape precisely rather than rounding it off. The effect is crisp and deliberate, adding brilliance without softening the edge of the design.

The band is where this ring gets interesting. A split shank opens below the setting into a negative-space triangle, creating an open architectural detail that ties back to the geometry of the stone above. From there, the two strands twist together into a pavé diamond band, carrying sparkle all the way down. It's a lot of considered detail, but it holds together because every element is working in the same direction.

Set throughout in 14K white gold, the cool metal tone complements the grey-green of the moss agate without competing with it.

Designed as a bespoke piece, this ring highlights:

• Hexagon-cut moss agate center stone with natural dendritic inclusions
• Full diamond halo following the hexagon silhouette
• Split shank with open triangle detail and pavé diamond band
• 14K white gold throughout
• A fully custom engagement ring with strong geometric character and organic detail

Moss agate draws people in because it looks like nothing else. Paired with the right setting, it becomes a ring that's genuinely hard to look away from.

If this design speaks to you, we'd love to help you create something similar built around your own stone and preferences.
