Dozens of tiny Magnesite crystals rest on the quartz base of this hand specimen. These crystals are in excellent condition - only a few are noticeably damaged - and none exceed 0.2" (4 mm) along any of their axes. All of them show good trigonal rhombohedral form, and all have a faint pink color due to hematite inclusions and the standard pearly luster. They are likewise transparent and moderately to very clear, containing hematite inclusions and internal cleavage planes. The quartz base is quite interesting; it is made up of several crystals that intersect with each other in such a way as to nearly confine themselves to one plane. They are transparent but are heavily included with a dull green substance that could be chlorite.
