Fabulous, razor-sharp crystals of magnetite, to over 1 cm, are all over this BIG specimen from Bolivia! The crystals are isolated on the matrix, which gives this specimen a real distinction from the usual specimen with crystals massed together. The other thing you do not see on this specimen is the usual number of corroded or damaged crystals - these are almost all complete and in fine shape. Great-looking gunmetal luster, too.
