As a returning customer, I can attest to Sylvia/PlusSoda's exquisite work!
If you are buying this as an anxiety fidget necklace, I HIGHLY recommend getting two - a polished gem and an unpolished/raw gem in chains just one length different from each other.
For instance, this is a 19-21" raw sapphire and a 21-23" labradorite.
I can fidget with one or the other, or when I need that extra tactile soothing, I have it right there and can fidget with them together, and no one around me is the wiser! Easy AND elegant!
