This diamond ring with wedding band is based on wolgade's diamond ring. http://www.makehumancommunity.org/clothes/diamond_ring_01.html It has a bigger diamond, and there is a wedding band. I have included a UV texture, but like most jewelry assets, this ring doesn't work "out of the box." It really needs two procedural materials, and the faces of the diamond should be shaded flat, while the ring should be shaded smooth. I have uploaded a .blend with diamond and gold materials for Blender Internal. http://www.makehumancommunity.org/content/diamond_and_gold_materials_for_blender_internal.html And for those who do Cycles, wolgade's Cycles gold and diamond tutorial is here: http://www.makehumancommunity.org/forum/viewtopic.php?f=4&t=13910
