Blue Moonstone(Good Quality)

Blue moonstone is the most well-known gemstone variety of orthoclase feldspar, a potassium aluminum silicate. It is a transparent to opaque oligoclase, a variety of plagioclase albite and sheet mica. Its name is owed to the almost magical, bluish white shimmer it exhibits, which closely resembles that of the moon. Moonstone is an excellent stone which brings calmness and emotional balance. It symbolises serenity & higher consciousness. Moonstone deposits are often found as constituents in feldspar-rich granitic and syenitic pegmatites all over the world. The most important moonstone deposits are from sri lanka and india. Other notable sources include australia, brazil, germany, india, myanmar (burma), madagascar, mexico, norway, switzerland, tanzania, and the united states.
