This is the Vary Rare Hard to find Vilya ring made by TNC.
This Ring is not available any more but I was lucky to find one On Ebay about a year ago in 2011. The Ring is made in Solid 10k gold and is remarkably very accurate compared to my Hansen 18k ring. The Jewel in the center appears to be sapphire as I tested it up to a lamp but is very dark almost black. I might replace the stone with A new Sapphire. You can see Comparison pictures in the last image of this posting.
