Gem Yellow Orthoclase


Itrongahy , Madagascar The name orthoclase is from the Greek for "straight fracture," because its two cleavage planes are at right angles to each other. Orthoclase belongs to the feldspar family of minerals that make up more than half of the Earth's rocky crust. Very rarely these common minerals form crystals that are gem quality. Orthoclase can be found as a transparent colorless, champagne, or yellow gem resembling citrine quartz or yellow beryl. This 30+ carat gem is unusual because orthoclase rarely occurs in a colorful transparent form. Its large size, fine transparency, and vibrant yellow color all contribute to its rarity. This is an exceptional gemstone originating from Madagascar, the most important source for gem-quality orthoclase. Weighing approximately 30.80 carats and measuring 19.86 x 16.03 x 14.04mm
