★★★★★★★★Available for immediate purchase★★★★★★★★ This is a large, loose ammonite pendant top from the Alberta province of Canada. Ammonite is a fossil gemstone miraculously formed when ammonites, which lived in the Cretaceous period (65 to 135 million years ago), fossilized and a pearlescent layer with iridescent colors formed on the surface. As you can see in the photos, each piece has a different expression and shines in various colors like black opal depending on the viewing angle. As you can see, a strong play-of-color effect can be observed. Without doublet or triplet processing, only surface coating is applied to protect the easily scratched iridescent aragonite layer. It is the most natural and minimal processing that makes the most of the original beauty of the material. Original design silver 925 bail is used. Hole drilling and bail attachment are processed in Japan. Please rest assured that this is a genuine natural ammonite, not a synthetic stone, glass, or plastic. Offered at a bargain price due to inventory clearance. Regular price: ¥16540. New and unused. ★Other loose stones are also available. Please see the seller's other listings.
