Teardrop wild horse jasper pedant

Teardrop wild horse jasper pedant
Bezel set in solid sterling silver 
 
Round wild horse pendant
The geological name is magnesite.
This stone was discovered in the mid-90's near the Globe copper mine in the Gila wilderness area of southern Arizona and only comes from there. Only a few years after the mine was opened, they closed it again, so any material on the market today has been stashed away in some prospectors garage. Some have called it Wild Horse Turquoise but it is NOT turquoise!
