Chlorastrolite (Greenstone) Half breed (silver, Copper Pendant HBGN-1

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.
