Green Sea Glass and Copper ring

I'm a massive fan of Copper and Green together, they're a match made in heaven.
This ring is size X, an oval of sheet Copper with a 9mm Emerald Green Sea Glass set in a Silver bezel and the back of the ring is also silver.
A lovely big statement piece.
If worn continuously it will make your finger green but I can head you in the direction of a liquid to coat the copper to prevent this. 
Copper is apparently very good for arthritis.
