1. Select the size of amber rough stone according to the size of the ring holder, and predict the shape of the ring surface (egg surface, flat surface, multi-faceted cutting, etc.). ) early stage. The bigger the size of the selected rough stone, the better. Peeling and impurity removal will destroy the rough stone. 2. Draw the shape of the ring holder on the "clean" original stone with a marker pen, roughly polish and shape it according to the black line, and cut out the periphery of the ring surface without trimming the top surface (front surface) first. Now I'm using a sander, which is faster, and a plastic file is ok, a little slower, without affecting the effect. Do not cut the ring surface in one step and then put it into the ring holder, but leave a slightly larger surface for later modification and polishing. 3. Adjust the size around the torus and install it on the ring seat. It should feel a little up. Note that the bottom of the torus must all fall into the ring support (inlaid ring support) without gap. Do not install the torus askew. Some rings are askew. You can adjust the angle with the top of the ring surface, so that the overall look is not so crooked, otherwise it will be more serious. 4. Always pay attention to the proportional relationship between the top of the torus and the bracket, neither too big nor too small. If you look at it while trimming, it is recommended to file it by hand. The plane is mostly egg noodles, and the shape of the top of the egg noodles can refer to the shape of the bottom. If the bottom is an ellipse, the top is an ellipse, and so on. Pay attention to the center when trimming the coat, or adjust the part between the coat and the waist. "Coat and waist" are at the same time. 5. Sandpaper polishing: I follow the process of 800,1500,300,5000 mesh. Of course, the smaller the mesh spacing of sandpaper, the better, and then cloth+toothpaste polishing, fine cloth with stripes. The ratio of the top to the waist can also be adjusted by sandpaper, of course, fine-tuning. 6. Glue installation (see my other blog for details). 7. You can take photos, box them or give them away.
