Let’s start with harder gemstones, which include diamonds and sapphires. The best at home cleaning method for these durable stones is simple and you probably already have these items on hand. Use a soft bristled toothbrush (a kid’s one works great) and gently scrub your pieces with warm water and a dash of blue Dawn dish soap. If the piece is older or hasn't been touched in a while, make sure to do this cautiously over a bowl or enclosed space. Why? Oftentimes, dirt and other particles will hold a stone in place so cleaning can cause the stone to become loose or even fall out.
When it comes to delicate stones (opal, emerald, topaz, moonstone, tourmaline, sunstone and onyx), cleaning them with warm soapy water and a soft cloth will do the trick. Make sure to avoid vigorous scrubbing and ultrasonic cleaners with these gentle beauties.
Pearls (aka our go-to summer accessory) will need to be treated most delicately of all. They should be wiped with a soft cloth after a long day of wear, and can occasionally be cleaned with warm soapy water. Don’t forget to apply your perfume, sunscreen, and hairspray before styling your pearls.
