MINERAL OF THE MONTH

February 2009: Polychrome Jasper

Polychrome Jasper

A new, but very small deposit of Polychrome Jasper has recently been found in the deserts of Madagascar. Specimens from this deposit were first sold at the Denver Gem and Mineral Show last September. Since I was going to the Tucson Show, I was commissioned to purchase larger and unusual mineral art specimens from friends who live in Lansing, MI. This was an awesome responsibility, but I enjoyed searching for and negotiating the purchase of higher-end specimens. As soon as I saw the Polychrome Jasper, I knew I had to add this to the list.

Polychrome jasper is a type of opaque, multi-colored chalcedony which develops in massive formations. Unfortunately, the formations found in Madagascar are few in number. It also goes by the name of Royal Savannah Jasper and Desert Jasper. It is believed to be one of the rarest jaspers in the world. In addition to the new pockets found in Madagascar, some deposits are also located in Australia.

Like other chalcedony minerals, it is thought to be a protective stone that improves self assurance and confidence. It can also help to foster a positive attitude. Professional guitar players are familiar with the stone because Polychrome Jasper is used to make high-quality guitar picks.
