Dear customer please take into consideration that the draw on agate stone ring can be different  on did you see on photo on site due to it is natural stone. Each ring is unique.

Copper will tarnish over time. To keep this unique and handcrafted item as its first day, I recommend you to keep it away from water. But even it gets darker you can simply clean it with a polishing towel. It will go back to its first condition easily.

Every piece is unique and handmade with love, positive energy and in an eco-friendly way!
