钻石订婚戒指 3D模型

High quality STL 3D model - Diamond_eng_ring021 Please note: All of our designs are made for actual production. Simply have the wax/resin model made, cast into the metal of your choice and have the piece finished. Prongs are intentionally high, so the gemstone setter will have enough prong metal to actually set the gemstones. Wall thicknesses are all thick enough for actual casting and polishing. I am a GIA gemologist and have 25+ years experience of making jewelry. Model is ready for prototyping on all 3D printers. Ring size - US 5.0 / 15.1 mm diameter. See pics for gemstone sizes and metal weights I am the author and creator of this model. This 3d model is selling exclusively on Turbosquid and can't be found anywhere else.
