Natural Ammolite and Diamond Pave 14K Gold Brooch Pin

A large natural ammolite brooch and pendant in 14K yellow gold, featuring a spectacular freeform iridescent ammolite cabochon bezel-set within a polished gold frame, accented by a diagonal pave diamond panel with approximately 2.00 carats of round brilliant diamonds including two larger bezel-set center diamonds. Measures 3.2 x 2 inches.

Product Specifications:
  • Item Type: Statement Brooch / Pin — also wearable as pendant
  • Metal: 14K Yellow Gold
  • Total Weight: 150.59 grams
  • Dimensions: 3.2 x 2 inches (approximately 81mm x 51mm)
  • Closure: Pin/needle brooch back with safety catch
  • Dual Function: Brooch and pendant

Ammolite Details:
  • Type: Natural Ammolite (fossilized ammonite shell)
  • Form: Freeform organic cabochon
  • Color Play: Vivid red, orange, green iridescence — mosaic/dragon-skin pattern
  • Setting: Full bezel, yellow gold

Diamond Details:
  • Type: Natural White Diamond
  • Cut: Round Brilliant
  • Total Carat Weight: Approximately 2.00 carats
  • Setting: Pave on diagonal corner panel; two larger stones bezel-set as accent points within panel
  • Color/Clarity: Not specified

About The Setting:
The 14K yellow gold mounting is designed to complement the organic, irregular form of the ammolite — a polished bezel frame follows the natural contour of the stone precisely, allowing the full surface of the ammolite to be the dominant visual element without interruption. A bold diagonal corner section in yellow gold carries the diamond content — a pave field of round brilliant diamonds studded with two larger bezel-set diamond accents — creating an asymmetric, contemporary design element that balances the organic irregularity of the ammolite with structured geometric diamond craftsmanship. At 150.59 grams, this is an extraordinarily substantial piece of fine jewelry — more sculptural object than conventional brooch — and the pin back on the reverse confirms its wearability as a true statement brooch.

About The Stones:
Ammolite is one of the rarest organic gemstones in the world, found almost exclusively along the eastern slopes of the Rocky Mountains in Alberta, Canada, and formed from the fossilized shells of ammonites — ancient marine cephalopods that lived over 70 million years ago. The iridescent color play visible on this stone — a vivid mosaic of red, orange, and green that shifts and intensifies with movement and light — is caused by light interference within the thin layers of aragonite that make up the shell, a phenomenon similar to that seen in fine opals but entirely unique to ammolite. This particular specimen displays the most prized color combination in ammolite — red and green — which gemologists and collectors recognize as the highest quality color grade. The 2.00 carats of round brilliant diamonds on the corner panel provide a sparkling white complement that makes the ammolite's color play appear even more vivid and saturated by contrast.
