This ring has been made using a tungsten core that has been filled with cultured opal. The opal has been set into the ring using a clear resin. Tungsten is a hard and durable metal that is scratch and wear resistant. Cultured opal is a man made product that sees minerals grown into crystals. It produces a product that displays different colours depending on how the light hits it.
This ring is sized as a US 13, Aus Z+. It can be made to any size though, please contact me if you would like one made.
