This nugget appears to be at least three intergrown platinum crystals, all of which are incomplete but all of which also show several crystal faces. The hollows of the specimen have a brown mineral coating which I cannot identify. The platinum itself has a rather dull metallic luster and slightly dark silver color. Close examination reveals that the surface is covered with tiny pits, which dulls the effective luster. Some of these are arrayed in a pattern which indicates that they may be due to a growth pattern.
