A good miniature with several colorless to white, translucent to transparent, well-formed, tabular crystals of bobdownsite to 1.5cm with excellent pearlescent luster. Some crystals are complete and some are not. A few kulanite crystals are on the piece for added interest. This is part of a lot of bobdownsite specimens found by Rod Tyson at a "private location" in 2005, subsequently characterized and approved in 2008 as a new species after first being sold as whitlockite. Bobdownsite is a basic calcium magnesium phosphate.
