This is a piece of gold ore - quartz with dozens of bits of gold leaf exposed on the surface. Several of the leaves are well (or entirely) exposed. The gold has, of course, a gold color and metallic luster. The quartz is just clear enough that some gold leaf can be seen penetrating a millimeter into the quartz.
