This hand specimen consists of a crust of heavily-intergrown Andradite crystals. These crystals are generally in good condition, showing a small amount of damage, and are so heavily intergrown that none can be considered individuals. The largest have maximum visible dimensions of 0.5" (1.3 cm) and are less than 50% exposed. They are of a variety of Andradite known as Melanite, and thus have a black color. Their luster is a slightly dull vitreous, and all are opaque. The crust that they comprise rests on a dull, pale brown base rock that I cannot define.
