Moonstone

Not really from the moon but with a galactic blue-sheen!

Moonstone is a quite terrestrial gem that is mined right here on planet Earth!

It is part of the Feldspar family and is usually formed with alternating layers of Orthoclase and Albite.

As light falls on these layers it is scattered in a phenomenon known as ‘adularescence’. The glow seems to ‘float’ across the gem as you change viewing angles, making it that much more captivating.

There are several types of Moonstone available in the market. Some of the most prized gems include transparent and translucent ones with striking blue sheen and transparent gems with rainbow effect.

Notable sources for Moonstone include Burma, Sri Lanka, Tanzania, India and Madagascar.

Moonstone is one of the birthstone’s for June.
