At Kirstin Ash, we use a variety of semi-precious stones and pearls, such as white topaz, moonstone, clear quartz, and citrine. Pearls form in natural shapes and sizes. Pearls can be vulnerable to many chemicals found in beauty products such as make-up, hair conditioners, perfumes, moisturisers etc. To clean semi-precious stones and pearls, use lukewarm water, gentle soap, and a soft cloth to gently buff away at the stone or pearl. Pat dry with a soft cloth.
