Sphalerite, Dolomite
Mid-Continent Mine, Treece, Picher Field, Tri-State District, Cherokee Co., Kansas, USA
Miniature, 4.5 x 3.2 x 2.9 cm
Another old Tri-State specimen, this one really striking and impressive: two huge sphalerite crystals, side-by-side - each about 3 cm across! They have textbook form, and sit on just a bit of accenting dolomite. If you are a collector of Tri-State material, you will know that this is an outstanding mini for what it is. Ex.
