Ammolite & Moissanite Heart Halo Pendant Necklace in 18k Yellow Gold over Sterling Silver

This pendant showcases the rare, shifting color of Canadian Ammolite in a bold 12mm heart cabochon. The gemstone glows with layered flashes of green, red, gold, and blue—those signature organic color waves that make Ammolite unlike anything else in fine jewelry. Its polished surface brings out depth and movement as the pendant shifts in the light.

A surrounding halo of Moissanite adds bright, crisp contrast, framing the Ammolite with clean white fire. Rhodium-tipped prongs sharpen the brilliance, while the warm 18k yellow gold finish enriches the gemstone’s natural color play. The balance of vibrant color and refined sparkle gives the pendant a modern, radiant presence.

Set in solid 925 sterling silver and paired with your choice of chain length, this is a rare-gemstone heart design that blends elegance, meaning, and standout color in a wearable, elevated silhouette.

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.
