Moonstone | Gemmology Lesson with Marie Chalmers

Let’s talk about Moonstone!

What is Moonstone?

Moonstone is part of the Feldspar family, which is one of the largest Gemstone families. It is called Orthoclase, which is its official name, and its sister is Amazonite. But within the Feldspar family, you also have other materials like Labradorite, but they are not as closely connected as Moonstone and Amazonite.

Different Colours of Moonstone

Moonstone comes in a variety of colours. From peach, to white, chocolate to Black Moonstone and even Rainbow Moonstone. Rainbow Moonstone is famous for having the most beautiful Schiller and that Schiller has a very specific name. It’s called Adularescence.

The Optical Phenomenon   

The phenomenon of Adularescence is exhibited in Moonstone. The term Adularescence came from some very specific material that was mined in Switzerland in Mount Adular.

It is created by alternating layers of Orthoclase and Albite. The layers are so fine, and they are actually similar in size to a wavelength of light.

They are very fine layers, and when our eye looks down, it scatters the light and gives that amazing Schiller effect that goes across the surface of the Moonstone.

It’s a very popular Gemstone because it has such an amazing colour and display and works fantastic in Jewellery. It looks especially nice when set into silver, as the colour and rainbow effect really stand out!

Rainbow Moonstone

Rainbow Moonstone is really highly prized. It has a white body colour and has amazing Adularescence, the layers give you a complete rainbow of colour across the piece, and that is one of the most popular Moonstones that we sell here at Chalmers Gems!

Does Moonstone come from the Moon?

No, it doesn’t! It is actually mostly found in Sri Lanka, but it is also commonly found in India and sometimes Brazil.
