This thumbnail piece consists of a single broken piece of a Sapphire crystal. It shows no evidence of crystal form- all surfaces show either conchoidal or uneven damage surfaces and the resulting vitreous luster. The piece has a beautiful blue coloration and no obvious zonation. It is transparent and moderately clear, containing several large internal fractures that would make cutting difficult.
