I am 3D Jewelry designer over 5 years and decide to share and sell my design. All models were created in reality before and completely tested. All models printed by 3D-printers and casted in Gold and silver before. The dimensions and Thicknesses are the exactly same as reality. STL files created with high resolution, 0.001 millimeters Tolerance, No Naked Edges, No Shell. There are two kind of files: 1_ without Gems for 3D printers and printing and casting with gold/silver 2_ With Gems for rendering and use for 3D software and 3D visualization. for this perpose I added OBJ file with Gems.
