(Internal #J490) You are bidding on an almost round, mosaic ammolite, oranges and greens, 7/16" long x 3/8" wide. Nice for making jewelry or as a display specimen.
For guy or gal, an awesome one-of-a-kind gift.
AMMOLITE CABOCHONS for jewelry: more precious than opals, these ancient pieces of shell fossils (ammonites a/k/a Chambered Nautilus Shells) from Canada absorbed the natural earth element aragonite when they fossilized which created these fantastic colors. Here's a photo of an example of polished ammonite from the Lethbridge mine, over 3 feet in diameter (2nd photo).
