Ammolite Oval Solitaire Ring in 18k Yellow Gold over Sterling Silver

This ring is designed to let the gemstone lead. At the center sits a 10×8mm oval Canadian Ammolite cabochon, an organic gemstone formed from fossilized ammonite shell. Ammolite is prized for its naturally occurring spectral color zoning, with rich greens and darker tonal flashes created by layered aragonite structure. Each stone is inherently unique, with no two patterns ever the same.

The setting is intentionally clean and timeless. A classic four-prong solitaire design keeps the profile elegant and wearable, allowing the Ammolite’s surface and natural coloration to remain the sole focus. With no excess metal or secondary stones, the design feels refined, balanced, and quietly distinctive.

Crafted in solid 925 sterling silver and finished in heavy 18k yellow gold vermeil, this ring uses thick micron plating for long-term durability and rich color, not lightweight cosmetic coating. The warm gold tone complements Ammolite’s earthy spectrum beautifully, creating a piece that feels substantial, intentional, and well-made. This is understated gemstone jewelry built around material quality and thoughtful design — not shortcuts.

Please note: Ammolite’s iridescent color play is entirely natural and varies from piece to piece. Each gem displays its own unique color pattern and intensity. We take care to photograph and select stones that reflect the overall quality and vibrancy you can expect to receive.
