Unique Design, one of a kind Moonstone Ring

This moonstone is a real stunner , the pictures don't really do it justice. 
It's 10x14mm set in a fancy, fine silver bezel. 
The ring itself is sterling silver, tapered between 6-12mm. Joined  together with a square silver bar of which the stone sits in top. I've fluted the ends slightly for comfort and added little dimple detailing along either edge. 
Just the one of these
