Jewelry is a kind of exquisite crafts with special materials. It will inevitably put forward different material requirements for different production materials. This is the fact. Among the various natural or synthetic gem materials used in jewelry, people have also proposed the rough shape, размер, цвет, transparency, material uniformity and defects, and special optical effects. Specific requirements.

В настоящее время, there are only more than 50 common natural gemstone materials (minerals, жемчуг, corals, и т. д.) used in the production of jewelry. In order to clarify the selection principle, the following common requirements can be put forward for them:

(1) The material is uniform, pure and flawless;

(2) The transparency is good, and the processed product is crystal clear;

(3) Bright colors;

(4) The surface of the finished product has a beautiful luster;

(5) The material has higher hardness and strength;

(6) The rough stone has a certain shape, size and quality, so that the processed product can meet the design requirements;

(7) Good chemical stability and wearing safety;

(8) Good processing performance of the material;

(9) It has special optical effects, и т. д..

В то же время, it should be pointed out that for each specific rough stone, generally only some of the requirements can be met, but not all of the requirements.

For precious natural gemstone materials, three more general requirements can be made as follows: “красивый, долговечный, and rare”, such as extremely precious diamonds.

(1) Beautiful as the fire of diamonds, the beautiful starlight of starlight rubies;

(2) Долговечный, such as extremely high hardness and wear resistance of diamonds, rubies and sapphires;

(3) The storage and production of rare minerals such as diamonds, рубины, sapphires and emeralds are very small.
