Description

Gemstone: Ammolite - 6.98 Cts.
Placenticeras sp.
Cretaceous
Bearpaw Formation
Alberta, Canada
21.76 x 13.39 x 2.38 mm

This pear-shaped Ammolite cabochon displays a bold interplay of warm and vivid color across a translucent surface. Saturated orange and golden tones dominate the upper field, transitioning into luminous green along the lower portion in a smooth, flame-like gradient. Subtle natural patterning within the material creates gentle movement beneath the polished surface, enhancing depth and visual richness. The high luster accentuates the organic structure derived from fossilized Ammonite shell material. This striking cabochon offers a vibrant and distinctive expression of one of nature's rarest gemstones.


Estimate: $400 - up.
