is a mixture of several minerals including Copper, Silver,
Nickel, Pyrite, Zinc, Iron and Manganese.
Pulsite is not considered a valid mineral species
but a mixture, or alloy-like coumpound. It is found
in Oregon and named after Jim Puls, the miner that discovered
it. Pulsite is associated with Manganese and can
be made into cabochons. The contrast of the bright metallic
mixture against the background of black Manganese is very attractive.
