Care and Cleaning
Proper care for birthstones depends largely on their hardness and any special properties. Harder gemstones like diamond, sapphire, and ruby (hardness 9-10) are durable and can be cleaned with warm soapy water and a soft brush. They are resistant to scratching but can still be damaged by hard blows.
Softer stones require more attention. Pearls, with a hardness of 2.5-4.5, are particularly delicate. They should be kept away from chemicals, including perfumes and hairsprays, and cleaned with a soft, damp cloth. Opals (hardness 5.5-6.5) are sensitive to rapid temperature changes and can crack if exposed to extreme dryness. They should also be cleaned gently with a soft cloth and mild soap.
Stones like peridot (6.5-7) and amethyst (7) are moderately durable but should still be protected from sharp blows and extreme temperatures. Ultrasonic cleaners are generally safe for hard gemstones but should be avoided for softer or porous stones like pearls, opals, and turquoise. When in doubt, using mild soap, warm water, and a soft brush is the safest method for cleaning most gemstones.
