This custom engagement ring centers on a striking emerald step-cut natural black onyx, framed by two faceted trillion-cut natural aquamarines for contrast and balance. Crafted in warm 14K rose gold, the design blends bold geometry with refined softness, creating a piece that feels architectural yet romantic.
The deep, inky black onyx anchors the ring with a strong visual presence, while the pale blue aquamarines introduce light and movement on either side of the center stone. Their triangular shape draws the eye inward, emphasizing the clean lines of the emerald cut and adding a subtle Art Deco influence to the overall design.
From the side profile, the setting reveals thoughtful structural details—open gallery work and carefully proportioned prongs that allow light to interact with the stones while keeping the silhouette elegant and wearable. The rose gold band softens the contrast between stones, lending warmth and cohesion to the composition.
Designed as a fully bespoke piece, this ring highlights:
- Emerald step-cut natural black onyx center stone (9×7mm)
- Two trillion-cut faceted natural aquamarine accent stones
- 14K rose gold setting with a refined, architectural profile
- Balanced three-stone design with strong geometric character
- A custom build focused on contrast, symmetry, and individuality
This ring is a beautiful example of how unconventional materials can come together in a timeless way—pairing bold stone choices with classic craftsmanship to create something deeply personal and enduring.
