Trust-Gems High Quality Rhodolite Garnet Facet Rough Gemstones

Diamond Cutting

The first improvements on the design of nature involved polishing of the faces of the crystal, which was called the "Point Cut. "As further refinement progressed, half of the crystal is cut, the creation of a cutting table. "At the time, Diamonds have been valued primarily for their brightness and hardness. Table Cut Diamonds appeared black to the eye. The Modern brilliant cut is the culmination of several hundreds of years of experimentation and development. Cutting a Raw Diamond into a faceted stone and polished gem quality is a multistep process. Each step is crucial for the final result. The steps are:

  • Marking
  • Cleavage
  • Sawing
  • Bruting (girdling)
  • Faceting

Marking: A rough stone is marked prior to cleaving or sawing to determine the grain or "cleavage", eliminate waste, and around inclusions or imperfections. The natural shape of the rough stone will also be an important factor in deciding how to cut stone. An octahedron can be divided into one or two brilliant round, but a square cut princess will result in less waste due to the square shape of the stone. asmacles asymmetric crystals are mainly used for fancy cuts. cubic forms are ideal for a square Princess or Radiant cut. computerizedhelium high-tech analizers oxygen and are now used to evaluate a stone before cutting:. Cleaving Cleaving refers to the division of a stone along its grain by striking it. A rough stone is cleaved if there are visible defects and / or inclusions which would prevent it from being done in a single stone. Cleavage is the tendency of crystalline materials to split along planes accurate. Thanks to its atomic structure, diamond can be cleaved in four directions parallel to each of the four octahedron crystal faces. Cleavage is a critical step as an error by the "sunset" could break the stone. Sawing: A stone saw is a thin disk of phosphor bronze. As the blade rotates, it continues to pick up or "recharge" itself with diamond dust, which is cutting agent. It may take several hours to the saw blade to cut through a rough diamond 1k. Bruting The crude is placed in a chuck on a lathe. Although the rough stone rotates on a tour of the diamond second diamond mounted on adoption are pressed against him, rounding the rough diamond into a conical shape. This step is also called the district or bruting.

Faceting: Facet for a "brilliant", a "blocker" or "lapper" will reduce the first 18 principal components, then a "Brightener" will carve and polish the remaining 40 facets. Cutting () and polishing of each facet is achieved by attaching the stone to a dop stick and pressing it against a hard cast renewable Scaife, or on the knees on a Facetron that was loaded diamond dust. During this faceting stage the angles of each facet must be cut to an exacting standard to produce a maximum brightness and maintain symmetry.
