Osis is the sister ring of Xsis, but it holds an oval stone and has rounded edges. It has a squared back, also called a Euro Shank to help keep the stone side upright on a finger.  You could opt to have a full round non Euro shank if you prefer.  The stone shown is an oval tanzanite in approximately 4 x 6mm.  Sapphires work well in this setting as well.  We could also make it for a round stone if you like. This one will get noticed.  The ring shown is in Polished finish, which shows off the smoothly curving surfaces.  We can make the Companion ring for Xsis work with Osis as well.

*Note: due to the asymmetric profile, engraving should be kept short to work best.  We suggest around 10 characters or less.
