Precious stones are fascinating, mysterious and reveal their full beauty in the hands of skilled craftsmen. After all, they are the ones who give them more life and shine.
Cutting consists of carving the stone in its raw state to enhance its natural color and shine. A faceted stone consists of: table (upper portion), crown (set of facets, just below the table), pavilion (set of facets located in the lower portion of the stone, which must end in a punctual extremity, the cuula) and girdle (meeting of the crown with the pavilion). There is little care in the process of stoning a gem. But do you know what are the steps it goes through until it gets beautiful and beautiful to your jewel? Follow with us.
1- Classification of the raw gem
Study of the optical properties of the gem, designing and visualizing dimensions and inclusions and evaluating its financial potential as a final product.
2- Training on the grinding wheel
In the formation or modeling stage, a closer approximation of the chosen cut shape is sought, leaving the gem as close as possible to the dimensions and angles of the table and pavilion and, above all, free of imperfections. In forming, the gem is pressed against a rotating grinding wheel.
3- Plumbing
The gem is fixed in a copper or wooden pen, using a resin, known as lacre, to fix it. The gem must be centered on the axis of the pen and in the horizontal position of the table/disc so that the facets do not lose their framing and the consequent loss of brightness and visual appearance.
4- Cutting or faceting
A faceted gemstone is one whose exterior is covered by flat, polished surfaces called facets. A lapping machine must allow the operator to insert flat and small surfaces at various angles ranging from 0º to 90º, called facets.
5- Polishing of facets
Final stage, where the smooth and flat surfaces of the faceting stage are polished, acquiring the shine that will provide the life of the gem. In this step, the faceted gem is subjected to strong pressure against the polishing disc, which is loaded with a polishing agent (aluminum oxide, carbon, cerium oxide, chromium oxide or silicon dioxide). The final product of this step must have flat facets, without visible grooves with the naked eye, providing maximum shine.Do you want to always be on top of news in the jewelry universe?
