DIAMOND & SAPPHIRE
These gemstones are known for their hardness, but still should be taken off when doing anything active or using chemicals. To maintain the gem’s natural sparkle, you can give the jewelry an ultrasonic bath and a good steam. If you don’t have access to an ultrasonic or steamer, don’t worry—using warm soapy water and a soft toothbrush to scrub the jewels works great!

OPAL, TOURMALINE, TOPAZ, MOONSTONE, EMERALD, SUNSTONE & ONYX
While we love these gemstones, they are a bit more delicate! Be sure to take off jewelry with these gems before cleaning with any chemicals, doing physical activities, or swimming. You can clean these gems with warm soapy water and a soft cloth,but avoid vigorous scrubbing and ultrasonic cleaners.

PEARLS
These beauties require the most care. They should be the last piece of jewelry put on when getting ready and the first to be taken off at the end of the day. Avoid using hair spray or perfume when wearing pearls. You can clean them with warm soapy water and a soft cloth.

ENAMEL
Enamel is super delicate and should be treated with care. Enamel may fade or chip over time with storage in direct sunlight, application of heat and aggressive wear. We recommend cleaning your enamel jewelry with only warm water, mild soap, and a soft cloth. Please avoid any at-home ultrasonics and harsh chemicals, which includes skin care products, cosmetics, dyes, colored shampoos & conditioners, cleaning products, and chlorine.
