It’s been used in jewellery for thousands of years and has been the subject of countless songs, poems, and symbols: Moonstone isn’t just an aesthetically pleasing gemstone, it’s also packed full of mystery and intrigue.

As you probably guessed, its name comes from its moon-like sheen, and is believed to have originated from ancient Roman beliefs that the stone was formed from frozen moonbeams. It’s a nice idea, but this gemstone is actually composed of two feldspar minerals: orthoclase and albite.

Still, that doesn’t detract from its beauty. Moonstone can come in a variety of colours including grey, peach, yellow or green - however, the most valuable and sought-after moonstones have a blue sheen, perfect clarity and a colourless body.
