This specimen consitst primarily of Hydroxyapatite which ranges in color from white to beige to a light yellow in color. The Hydroxyapatite is present in both a botryoidal habit and as pseudomorphs after unidentified, striated, bladed crystals. There has been much speculation as to the identity of the original crystals with Stibnite, Hemimorphite, Vivianite and Gypsum having been proposed as precursors. There is also present much unidentified black material which in places forms spherical aggregates. This material is quite hard and cannot be scratched with a dental pick. The specimen fluoresce a yellow/creamy color under both SW and LW UV as depicted in the last photo.

Condition: Excellent

Flaws: Nothing Appreciable
