Russian Charoite & African Amethyst 18” Statement Necklace

Charoite is a rare violet gemstone that can only be found in the Chara River area of the Murun Massif in Russia. It's named after the river. Handmade Necklace, Sterling Silver Necklace, Handcrafted Necklace. I purchased these from an online dealer from India. I've not had the silver, or the carnelian tested, but I've been purchasing from this vendor for over five years, and I wear this jewelry daily. The silver tarnishes, just like you would expect silver to tarnish. It's marked 925. However, because of this, I have priced this as fashion jewelry.
