DrillingThis technique is used if the lapidarist wishes to create a hole through or in Rubber Cutting Machine a gemstone. This technique is most suitable for transparent stones. It may even be harvested like pearls or organic material like amber, just as long as it has aesthetic appeal. For round gemstones, a belt sander may be used to ensure smoother and rounder curves. Everything else was labeled as semi-precious gemstones. Drilling tools may be rotating or ultrasonic. SandingThis process is similar to grinding but uses finer abrasives. This way, the barrels vibrate rather than rotate. TumblingA gemstone that is placed in a rotating barrel filled with water and abrasives is tumbled for polishing.Sawing The main tool used in sawing is a copper or steel blade with diamond grit on the edges.The Ins and Outs of LapidaryLapidary refers to the process of cutting and polishing gemstones.

GrindingDiamond-impregnated grinding wheels made of silicon carbide are used to grind gemstones and shape them into a pre-form. Cut gemstones are then polished into several forms such as sculptures, intaglios, cameos, mosaics, intarsias, inlays, spheres, beads, cabochons, and faceted stones. Common cutting techniques include tumbling, drilling, polishing, lapping, sanding, grinding, and sawing. In the old days, precious gemstones only referred to the Big Three: emeralds, sapphires, and rubies. Tumbling techniques are also used to polish metal jewelry pieces. This is usually an alternative to faceting for gemstones that possess too many inclusions. Materials like silicon carbide and diamond, due to their hardness, are used for cutting gemstones in a progressive abrasion process. Rough materials are left uncut and unpolished. The cabbing machine then twirls and creates a round smooth surface top and a flat or slightly rounded bottom for the gemstone. Liquid substance is also used to prevent both the stone and tool from overheating. It is often performed as a follow-up after grinding for removing scratches caused by the previous cutting technique. Water or oil is used to eliminate cutting debris and prevent the blade and stone from overheating. Sometimes, vibratory machines are used in lieu of rotating barrels.It is easy to feel intimidated and out-of-place when you are visiting a high-class jewelry store for the first time.

The process however is similar to sanding and grinding. Today, new techniques like grooves and concave facets are used to create new looks for faceted gemstones. Compounds like aluminum and chromium oxide are, on the other hand, used for polishing gemstones. Cobbed materials are referred to as fractured.CabochonsCabbing or cabochon cutting is achieved by gluing or dopping the gemstone into a metal or wooden dopstick or simply holding it in place. LappingA lap, which is a flat disk that is either vibrating or rotating, is used to create flat surfaces rather than round ones.The Meaning of GemstoneA gemstone may be a rock, mineral, or even a petrified material that is cut and polished to be used for making jewelry.Faceted StonesGemstones that have faceted forms reflect brilliant color and clarity from all sides and at all light levels.
