This Montana sapphire has the best blue color you can imagine so deep and we'll saturated. It has one small flaw that will be covered by a prong in setting this does not take away from the stone at all. This piece was cut by Mike Soebbing and he did a perfect job capturing the excellent luster while keeping the deep blue color. Dont miss this opportunity to get this stone as it is extremely rare to get this color from Montana. This stone has been heat treated and is 8.35mm
