This simple, yet elegant ring is made up of a single 8mm Black Obsidian bead and stainless steel wire. Stainless steel holds up to the elements, and will not tarnish or discolor, so it is great for every day wear! The circular shape of the gemstone rotates to allow you to fidget when you feel uncomfortable without drawing too much attention to yourself. Since each ring is handmade, expect slight variations from the picture shown. The ring will come packaged in a charming box, perfect for easy gifting! Obsidian is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is hard, brittle, and amorphous; it therefore fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools. All my jewelry is handmade and made with patience, care and love. If you have any questions about this item, or any other items in my shop, please feel free to contact me.
