Eifel Mts., Germany
Sanidine is a Potassium Feldspar that is found in various localities around the world, but some of the finest crystals of Sanidine are found in the Eifel Mountains in Germany. These crystals are often small (typically a few mm) when gemmy, so you rarely find any pieces that are large enough to cut a stone. This stone is incredibly large by German Sanidine standards. The stone is a very attractive straw color, nearly virtually eye clean clarity and a "Cut Corner Square" cut. These gems are not very common, and are some of the more rare of the gem Feldspar stones around.
