This beautiful teardrop pendant is made of ammolite. Ammolite is an opal-like organic gemstone made of the fossilized shells of ammonites, a group of extinct marine mollusc animals.
 
It is found primarily along the eastern slopes of the Rocky Mountains of North America. Significant deposits of gem-quality ammolite are only found in the Bearpaw Formation that extends from Alberta to Saskatchewan in Canada and south to Montana in the USA. However, small deposits have been found as far south as Central Utah which also contains gem-quality ammolite.
  
Ammolite can come in any color in the rainbow but most are green and red. Blue and violet are rare and, typically, more valuable.
 
Ammonite was named after the Ancient Egyptian god Amun, who was represented with ram’s horns.
hardness: 3.5-5.5 transparency: opaque, thin sheets used in assembled stones may be translucent to transparent luster: vitreous to resinous refractive index: 1.520-1.670  This pendant is fashioned in sterling silver and includes the chain.
 
As ammolite is rare, no two are alike, you will receive a similar, but not exact piece.
