How do you clean moonstone jewellery?

Moonstone jewellery needs a gentle clean, just lukewarm water, a few drops of mild soap, and a soft cloth. Keep away from abrasive brushes, ultrasonic cleaners, and any harsh chemical soaking.

Moonstone is a feldspar mineral, and it has a Mohs hardness of around 6 to 6.5. It also shows perfect cleavage, so it can get scratched or split if it takes a hit. The delicate adularescence, that glowing light effect, can fade quickly when you use forceful cleaning methods or when it meets common household solvents.
