Raw natural quartz crystal stone. Has healing quality. Quartz is the strongest enhancing stone in the mineral kingdom & helps reignite our true identity while showing us the path towards enlightenment. Quartz crystal is actually a mineral, one of the most abundant minerals in the Earth' continental crust, composed of silicon and oxygen. Quartz can be icy clear or have inclusions, veils, bubbles and various colors. It's also known as rock crystal, crystal quartz, universal crystal or clear quartz. Many of the jewelry items listed are antique, vintage, and/or pre-owned. Items have had a life before I found them. Items may show evidence of that previous life; signs of wear, dents, scratches, oxidation, or broken stones, etc. I strive to be accurate & transparent in the descriptions of these pieces. I'm not a gemologist. I choose pieces based on their overall aesthetic & how well they accessorize. I try my best to accurately describe the stones in my jewelry items, but cannot absolutely guarantee them. I want the true age of the pieces to be represented, so I do not perform any type of cleaning or polishing. If the item is oxidized when I acquire it, that is precisely how you will receive it.
