Gem naming

Naming of natural gemstones
The Confédération Internatio nale de la Bijouterie (Joaillerie et Orfèvrerie, CIBJO) stipulates that the name of the gemstone should be the name of the mineral or the commercial name passed down from history; the jade is passed down from the main mineral name or history of the mineral combination. Commercial name; bio-gems use traditional bio-gem names. The name of the gemstone plus the name of the place of origin, country or other gemstone is not allowed as a suffix.
Gem naming
The name of the gemstone, usually the name of the mineral. If a mineral has only one gemstone variety, the gemstone uses its mineral name; if there are more than two gemstone variants, the commercial name passed down from history is used; if there is no commercial name passed down from history, it is given in the name of the mineral. The prefix of the gem color.
For example, rubies and sapphires, red and blue gem-quality corundums , have been traded under the trade name; emeralds and aquamarines, respectively, are gem-quality beryls of brilliant green and navy, also passed down from history. Business name.
Jade naming
The name of the jade is usually also the name of the major mineral in the mineral portfolio or the commercial name passed down from history. However, there are more jade species named after the place names in the market. The phenomenon of multiple kinds of jade materials is more common, not as uniform and standard as gemstones. For example, jadeite has three commonly used titles, jadeite named after jadeite minerals, jadeite named after the commercial name, Burmese jade named after the place of origin, etc. Serpentine jade has serpentine jade named after minerals, and also has the name of the place of origin and the commercial name. Such as Yan Yanyu, Kunlun jade, Korean jade, Bao Wenyu and so on.
Name of biogem
There are not many varieties of bio-gems, and the names are also uniform, such as pearls, amber, ivory and so on.

The name of the artificial gem
Name of synthetic gemstone
Synthetic gemstones commonly found on the market, mainly those high-grade gemstones with relatively simple chemical composition and relatively high price, such as synthetic diamonds, synthetic rubies, synthetic sapphires, etc., should be marked with the word "synthetic" in front of the gemstone, otherwise it belongs to deceitful acts.
Imitation gems
Imitation gemstones do not have their corresponding natural gemstones. Their names should be marked with the word "copy" or the name of the real material. Otherwise, it is also a deceptive act.
Combination of gems
The name of the combination gemstone should be indicated in its category, such as: Opal two-layer stone or imitation diamond foil lining.

Manually optimize the naming of natural gemstones
There are many methods for manually optimizing natural gemstones, such as heat treatment, thermal diffusion, dyeing, coloring, radiation, and the like. In addition to the heat treatment method, the gemstones have the same stability and durability as the natural gemstones, and the gemstones treated by other methods are different. Therefore, the International Jewelry Federation stipulates that in addition to the heat-treated gems, the gems optimized by other methods must be added with the word “optimizationâ€, otherwise it is considered cheating. Such as: optimizing jade, optimizing sapphire, optimizing diamonds, etc.
SF-200 is a Hand belt type resistance Forming Machine which is the best selection for mass production.Easy adjustment,operation and long life.
SF-201 is the same as SF-200,Beside above ,they are Loose Tape resistance Former suitable for vertical or horizontal shaping of resistors and diodes.
SF-202Component bending forming machine is bulk, with resistance and diodes are available.Foot cutting, bending can be strengthened, foot long span can be adjusted.
SF-208FB Axial automatic resistor machine has three Models for Processing Different Type of Packing.
SF-206 The bulk Resistor Former has three models each for both M&C types.The difference are listed as follows:â‘ SF-206-MA;SF-206-CA for loose packed components â‘¡SF-206-MA;SF-206-CB for taped packed components â‘¢SF-206-MA;SF-206-C for using on both taped and loose packed components.
SF-208 Equipment K Type Resistance Molding Machine has three Models for Processing Different Type of Packing.â‘ Loose packed Model(SF-208-FA).â‘¡Taped Model(SF-208-FB).â‘¢ Loose packed/taped combinative Mode(SF-208-F).
SF-206MB The axial lead former m type has three models each for both M&C types.The difference are listed as follows:â‘ SF-206-MA;SF-206-CA for loose packed components â‘¡SF-206-MA;SF-206-CB for taped packed components â‘¢SF-206-MA;SF-206-C for using on both taped and loose packed components.It is also means automatic resistor forming m machine.
