Found in various seas and rivers from the saltwaters and freshwaters of Japan to the Red Sea and Persian Gulf, pearls exhibit a natural shimmering quality. Delicately formed in shellfish such as oysters and mussels as a natural defence mechanism against irritants, pearls represent peace and nobility. Hues of white, white with pink and black or brown can be found on a choice of pearl jewellery. Extra care should be taken when wearing pearls as they are sensitive to acids, dryness and humidity.
Moh hardness: 3 (1 softest to 10 hardest)
Pearls are an organic stone and are soft and delicate. Pearls have a low resistance to heat and chemicals so these things should be considered when caring for pearls. Pearls can be easily scratched by other jewellery so should be stored in a soft jewellery pouch or the presentation box they were bought in. Pearls may require restringing annually or on occasion depending on how much they are worn. Pearls should be cleaned using water and a dried with a soft jewellery cloth. Harsh chemicals and detergents should be avoided as these will cause erosion. Pearl jewellery should be put on last when dressing to avoid contact with cosmetics such as perfume and hairspray.
