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 crysatllized. In fact, It LOOKS twinned - I do not know what twinning in sperrylite SHOULD look like, but a hunch says this may be it.
