Signet Ring

This is the Signet ring for our family. I already made the basic shape of the ring (in Rhinoceros) and prepared it for 3D print. And than it will be caste in white gold and in the middle I will use stone called "Black coral".
At the moment I am working on a coat-of-arms (so, the lion on the render picture is only provisional and it`s made in Photoshop). For this purpose I am using interesting side about Heraldry.
