Aesthetically perched high on its matrix is a glassy and gemmy crystal, 5 mm across, of xenotime-Y (a rare yittrium phosphate). This is a small crystal, admittedly, but its so glassy and lustrous and gemmy that it surely must be among best of species on a gram for gram basis, and was highly valued ($300) when Marty bought it from dealer Herb Obodda after a summer trip to Pakistan in 2006. It is a piece for quality and surprise, and I think would puzzle most folks about its identity.
