Calcite Twin
Mekhtar, Loralai District, Balochistan, Pakistan
5 by 4 by 4 pounds (12.7 x 10.2 x 10.2 cm). 6 pounds (2.7 kg). Custom lucite base.
A large, twinned calcite exhibiting a unique yellow-green color with minor purple fluorite seen peeking out on both the front and backside of the specimen.
Calcite is a triagonal carbonate mineral found primarily in association with limestone. This particular specimen's twinning is dramatic and the yellow-green faces show an interesting growth pattern or etching.
