In the previous article, I shared the physical properties and some magical characteristics of gemstone beads. In this article, I would first like to briefly introduce you to the gems that are new to this industry and want to learn about pearls and cabochons. Let's look at the meaning of:
Gem - A precious or semi-precious stone that can be used as a jewel once cut and polished.
cabochon: a very polished jewel carved convexly but without facets
Ranking of precious stones
The ranking of gems and pearls is less formal than the ranking of gems as a whole. Nevertheless, there are some generally accepted rules that determine the score assigned to a stand. The score is awarded on the basis of a letter with A being the best and "D" the worst. Note that "D" can be exactly what you want for a specific project, so do not dismiss it as worthless. Sometimes you can see gem grades of A A A and A A. These are real gem grades with A A A almost perfect. It is rare that stones of this quality are cut into beads. They are worth more than faceted gems. The general quality of the thread stones usually comes from a combination of the classic qualities of gemstones that are color, cut and clarity. I'll include more in the next article, but as far as I know, you may have some idea of gems.
There are different types of gems such as ruby, emerald, sapphire, amethyst, citrine, aquamarine and many others. These precious stones are found in different parts of the world and are imported by suppliers and exporters directly from the mines in the form of rough stones. These raw stones work as raw material for further processing.
Shape and size:
These stones with rough edges are also decided to convert into oval, round, square, faceted, chip, smooth, etc. and the required size.
Cutting and polishing:
The skilled craftsmen of the manufacturing unit cut and polish the stone with the help of modern machinery.
However, most are cut and polished to be used as jewelry. The two main classifications are stones cut as smooth, domed stones called cabochons, and stones that are facetted by polishing small flat windows called facets at regular intervals and at exact angles.
Opaque stones such as opal, turquoise, variscite and so on. are usually cut into cabochons. These gems are designed to show the color or surface properties of the stone as in opal and starry sapphires. Grinding wheels and polishing agents are used to grind, shape and polish the smooth shape of the stone dome.
Gems that are transparent are normally faceted, a method that best shows the optical properties of the interior of the stone by maximizing the reflected light perceived by the viewer as a sparkle. There are many forms commonly used for faceted stones. The facets must be cut at the appropriate angles, which varies depending on the optical properties of the stone. If the angles are too steep or too low, the light will pass through and will not be reflected back to the viewer. The facetteuse is used to hold the stone on a flat cover to cut and polish the flat facets. Rarely, some strawberries use special curved tricks to cut and polish curved facets.
Finally, these gems are used to make beautiful jewelry. There are many types of tools for connecting beads and metals for making necklaces, pendants, rings, etc.
Now that you know the basics, how do you gain practical knowledge? Visit the manufacturing facilities of wholesale suppliers and exporters and note how they are processed.
