Turquoise is one of my favorite stones because . . . it's gorgeous! Unfortunately it's been really difficult for me to find turquoise in the past year due to a turquoise mine closing down, so if you're lucky enough to have purchased turquoise jewelry from me or anyone in the past, take care of it!
I'd like to emphasize that cleaning turquoise is different from other stones in that you can ruin turquoise. Bottom line : turquoise doesn't do well with chemicals. Don't jump in a chlorine pool with your turquoise, or spray perfume, bug spray, sunscreen, or toxic waste onto your turquoise. If it's looking a little gray or dull, it may just be dirty. I try to wipe the turquoise off with a damp, soft cloth until it's clean.
It’s also safe to clean turquoise jewelry with warm, soapy water, but it should never be cleaned with steam or ultrasonic cleaners. Some turquoise is treated to improve its surface appearance, and heat or solvents can damage the treated surfaces.
Hope this helps you show your turquoise some love during its birth month!
