Half-breed (Silver/Copper),Chlorastrolite (Greenstone) & Datolite Pendant HBYDGN-2

Chlorastrolite is the “official state gem” of Michigan. It is a variety of the mineral pumpellyite and is found primarily as a small, green, rounded beach pebble, showing a turtleback pattern. Greenstones can still be found on Isle Royale and on some of the mine waste piles of the Copper Country, although it is a rare mineral.


Half-breed (Silver/Copper)
Half-breed usually refers to a natural mixture of white native silver & red copper. Unique to the Upper Peninsula of Michigan and corresponding areas of Canada across Lake Superior are masses of silver and copper referred to as : Ëœhalf-breeda'. These consist of crystalline intergrowths of these two metals, usually of a reniform habit except when found underground.

Datolite
Datolite is a borosilicate mineral (hardness: 5-5.5). It is associated with native copper deposits in Michigan’s Keweenaw Peninsula. The characteristic ‘cauliflower’ shaped nodules range from 1-12 inches. The rarest colors are yellow, orange, green and red. White and pink are more common. At times specks of copper or silver appear with the datolite. This rare mineral is found in old waste rock piles and in Lake Superior.
