Sperrylite is one of the world's great platinum minerals in crystalline form and specimens of quality, AND of size, came only from a small deposit found here some years ago. Now, they are very scarce on the market. This is a spectacular display-quality piece with good aesthetics. The contrast of colors, between the brassy matrix of massive chalcopyrite and the mirror bright luster, and silver color of sperrylite, is spectacular. Several crystals of sperrylite, a platinum mineral, dot the surface of the chalcopyrite matrix. The largest crystal is 1.0 cm across and it is very sharply crystallized. In fact, It LOOKS twinned - I do not know what twinning in sperrylite SHOULD look like, but a hunch says this may be it. It certainly is more complex than other crystals I have seen.
