One surface of this rock is coated with a druze of bright green uvarovite garnet crystals. While all of these crystals are tiny, they have a variety of sizes and the color varies in depth, as the largest crystals are transparent, vitreous, and well-formed, while the smaller crystals appear less intensely green, and a sizable fraction have a greenish-white appearance. It appears that the uvarovite coated a narrow crevice in the host rock, and this is one side of the crevice. The lighter colors (due to fractures and incomplete crystal surfaces) are the contact surfaces where the two sides touched.
