The turning green is a natural process that is due to your skins reaction with the copper. However, my rings are sealed to prevent this, but it too the depends on how the body of each person reacts to it. Since I can’t promise this, there are still ways to prevent this: avoid contact with water and sweat. Sweat can happen if it’s worn for multiple hours. Let your finger rest by washing your hands and drying it fully between this hours. If it ever does turn green just rinse with water and soap.

No. They are excellent quality.

Each piece is exactly as pictured, described and securely wrapped to prevent any damages. However, I will accept if another item was sent by mistake or if the ring doesn´t fit. I could also accept exchanges, although buyer would be responsible for shipping costs.

Copper. It is done through the art of Electroforming, which is an electrodeposition process where the metal bonds with the conductive surface. Prior to that, I handmade the design with clay that is attached to the stone.

They are 100% natural with no artificial process done to the stone, unless expressed in the description. However, almost all of them are cut to the desired shape, so they are not exactly raw.

No. All the jewelry I put in the listings have the copper already oxidized with a dark/brown look and I also seal them to mainting it’s quality. However, the sealer may not last forever and it may lose its shine, but to keep the surface gleaming, just put clear nail polish to it and it will go back to the way it was!
