Moonstone is composed of two feldspar species, orthoclase and albite, merged together in alternating layers.
Moonstone can have a range of colours, including white/cream, yellow, blue, grey, peach/pink, and green. The structure of moonstone creates a shimmering effect known as adularescence or schiller. Pale moonstone with a striking blue adularescence is very popular. Moonstone has a hardness of 6-6.5 on the Mohs Scale, so it is quite susceptible to scratching.
Moonstone is found in many countries including the USA, Mexico, Sri Lanka, Brazil and India.
It is believed that moonstone stabilises emotions and promotes inner strength and calmness, making it an ideal stone of “new beginnings”. Since 1970, moonstone has been the state gem for Florida to commemorate the Moon landings which took off from there.
