Since every gemstone has its own specific conditions of formation, chemical composition and internal structure, there is still no uniform classification scheme in the world. How to classify gems scientifically and reasonably is a topic of common concern in the international jewelry industry. В настоящий момент, countries around the world agree with the classification of gems […]

На природе, all materials that have bright colors, кристаллы, и блеск; pure texture, hard and durable; excellent craftsmanship; rare characteristics that can be processed into jewelry and handicrafts can be called gems. These materials include: natural mineral crystals (single crystals and crystal aggregates), amorphous rocks, and natural organic materials and man-made materials. Вообще говоря, unprocessed […]
До сих пор, больше, чем 4,000 kinds of minerals have been discovered in the world, of which nearly 600 can be called gems, и примерно 30 обычные драгоценные камни. The factors considered for the classification of gems include: the genetic type of gems, the habits and traditional culture of the international jewelry industry, and the traditional Chinese […]
The reason why gems are called “сокровища” is their beautiful color. So what is the attractive color of gems? Where did it come from? Color is an electromagnetic wave that can be felt by the human eye with a certain wavelength. Its wavelength range is about 400-700 nm in the electromagnetic spectrum, также известен как […]
In chromatology, the three elements of hue, lightness and saturation are used to describe colors. Hue, also called hue, refers to the distinguishing characteristics of red, апельсин, желтый, зеленый, голубой, синий, и фиолетовый. The hue depends on the selective absorption of visible light by the gem. Brightness, also known as brightness or hue, является […]
Красота драгоценных камней прежде всего в цвете. Кроме того, прозрачность и блеск – все его прелести. Прозрачность – это способность драгоценного камня пропускать свет.. Обычно делят на: прозрачный, полупрозрачный, полупрозрачный, полупрозрачный, непрозрачный. Прозрачность: легко увидеть сквозь свет, прозрачное дно, the outline and details of the scene can be clearly […]
The ability of a gemstone to resist pressing, надрез или шлифовка называется его твердостью. The hardness of a gemstone is related to its chemical composition, chemical bond and crystal structure. Hardness is one of the three essential elements of gemstones, and it is also a problem that must be paid attention to in gemstone […]
Electrical conductivity is the ability of a gemstone to conduct electricity. It largely depends on the type of chemical bond. Gems with metal bonds are highly conductive because they have free electrons in the crystal structure, while ionic bonds or covalent bonds are weak or non-conductive. Кроме того, the conductivity of gems is also related […]
Под действием внешней силы (например, избиение, сжимая, и т. д.), Кристаллы драгоценных камней могут регулярно раскалываться в определенном направлении, образуя более гладкую плоскость.. Свойство называется расщеплением. Эти потрескавшиеся поверхности называются поверхностями скола.. Поверхность скола связана с атомной структурой минеральных кристаллов., and is usually the weaker […]
Inclusions in gemology refer to three aspects: (1) The solid, liquid and gaseous substances inside the gemstone are called solid, liquid and gaseous substances. (2) The color zoning and distribution or growth pattern of gems. (3) Fractures, cleavage and cracks. The presence of inclusions often affects the quality of gemstones, but the regular arrangement of […]
