Sterling Silver Fossil Ammonite, Trilobite, Quartz Pendant

The relatively abundant mineral smoky quartz ranges in color from almost black to nearly colorless. Gem quality specimens are mined from the Swiss Alps and from Pike's Peak in Colorado. Dark smoky quartz is sometimes heat-treated to give it a lighter color which appears more brilliant when cut.

Trilobites were ancient sea-dwelling arthropods that lived in shallow coastal areas. They survived for approximately 350 million years beginning in the Cambrian period and are the earliest animal to exhibit evidence of eyesight in the fossil record.
