New Ring gems.

Changed the Ring Gems. I like these ones.  I made them with Cheeta3D.

I started with a truncated Icoshedron (polyhedera)and flattened it. Then took anther truncated icoshedron (polyhedera1) and shrunk the x and z scales rotated it 30 degrees in P: and subtracted it from polyhedera. I then made three copies of polyhedera1 and rotated them to 90,180 and 270 degrees in H: subtracting them also from polyhedera. I think it is a nice looking gem, the yellow and hole both show clearly.
