3D of jewelry

I am in need of a 3D model of a piece of jewelry, specifically a ring. I have specific elements/themes I would like included in the model design, and will share these details with the designer after selection. My preferred file format for the final 3D model is STL. The project must be completed accurately and to my satisfaction, so I am looking for experienced professionals with a reliable portfolio in 3D modeling. If you think you have what it takes to produce the piece, please submit your offer and I look forward to working with you.
