Quantity: 7 inch strand (aprox 6-7 beads
Length 20-35 mm
Width 22-35 mm
Height 10 -18 mm
Material: Ammonite (fossil) (Ammolite)
Color: brown black tan fossils
Grade: very good Rare
Details: These are RARE natural Fossils. Almost all show the reddish-orange or mother-of-pearly iridescence of the original shell that dates back to prehistoric times. They vary in color from a rich cocoa brown with whitish and light tans, some are light cafe au lait with darker striations. Almost all have at least some of that opalescene that is typical to ammonites. Each bead is more fascinating than the next!
Because these are natural fossils, please expect some to show their million year old patina. Please look at ALL the photos to see details of the beads you may receive.
Your 7 inch strand will be chosen at random from the lot shown. Each strand has approximately 6-8 fossils.
They vary in sizes from approximately 20-35 mm. We cannot break up the strands.
They have a smooth polished surface but because these are NATURAL fossils there is some surface fractaling and pitting and cracking due to the inconsistencies in the natural shell and the age of these. They are good specimens for jewelery artists or collectors.
About Ammonite (fossil) (Ammolite):
Ammonites, as they pertain specifically to the order Ammonitida, are an extinct group of marine. Fossils, such as many found in Madagascar and Alberta (Canada), display iridescence. These iridescent ammonites are often of gem quality (ammolite) when polished. In no case would this iridescence have been visible during the animal's life; additional shell layers covered it.
Ammonite fossils became less abundant during the latter part of the Mesozoic, with none surviving into the Cenozoic era. The last surviving lines disappeared along with the dinosaurs 65 million years ago in the Cretaceous-Tertiary extinction event.
