Spring 2014

A big, (4.5 CT) complex Diamond crystal with a fine glassy, vitreous luster. An older specimen, vintage 1980's that presents well and shows some very intricate crystal modifications. Also note there is a distinct color shift from yellow to a green or brown green hue in different light sources. A very good crystallized example of the element (Carbon) that humans are made from!
