ABOUT AMMOLITE AS USED IN ESTATE JEWELRY
ORIGIN OF NAME
Named after the fossilized extinct shellfish, ammonite, from which it is comes from.
Ammolite was first sold as a gem in 1962. Major production of ammolite followed in 1983.
LEGENDS A few Feng Shui followers believe that ammolite consumed cosmic energy from the universe, and has circulated that energy and is now returning that energy resulting in the stone generating health, wealth and enlightenment.
Ammolite is a form of aragonite made from a fossilized, extinct shellfish called ammonite.
Ammolite is often kept in a freeform shape to maximize carat weight, if it is untreated or not made into a doublet or triplet. Extra fine ammolite should clearly display at least three or more sharp, brilliant colors and should not have dark areas. The most valued ammolite easily displays the full spectrum of colors. One of the highest prices per carat of ammolite was $8,000, one stone that weighed 250 carats. Red and brown are the more frequently found colors of ammolite, and thereby command the lowest values.
Ammolite is mined only in Southern Alberta, Canada. It was originally discovered by the Blackfoot Indians.
Ultrasonics cleaners and steam cleaners should be avoided, as should rough wear or daily wear, heat and chemicals. To clean, use a soft cloth or brush and light, cool soapy water. Heat and acids will cause ammolite to loose color and iridescence. Purple and blue ammolite are more brittle than red.
