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. 現在のところ, countries around the world agree with the classification of gems […]

自然の中で, 明るい色のすべての素材, 結晶, そして輝き; 純粋な質感, 硬くて耐久性のある; 優れた職人技; 宝飾品や工芸品に加工できる希少性の高いものを宝石と呼びます。. これらの材料には以下が含まれます: 天然鉱物の結晶 (単結晶および結晶集合体), 不定形の岩石, 天然有機材料と人工材料. 一般的に言えば, unprocessed […]
これまでのところ, より多い 4,000 kinds of minerals have been discovered in the world, of which nearly 600 can be called gems, and about 30 common gems. 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 “treasures” 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, とも呼ばれます […]
色彩学において, 色合いの三要素, 明度と彩度は色を表現するために使用されます. 色相, 色相とも呼ばれます, 赤の際立った特徴を指します, オレンジ, 黄色, 緑, シアン, 青, そして紫. 色相は宝石による可視光の選択的吸収によって決まります。. 輝度, 明るさまたは色相とも呼ばれます, です […]
The beauty of gems comes first in color. 加えて, transparency and luster are all its charms. Transparency refers to the ability of a gemstone to transmit light. Usually divided into: 透明, 半透明の, 半透明の, 半透明の, 不透明な. 透明性: easy to see through the light, clear bottom, the outline and details of the scene can be clearly […]
The ability of a gemstone to resist pressing, スコアリングまたは研磨はその硬度と呼ばれます. 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. 加えて, the conductivity of gems is also related […]
Under the action of external force (such as beating, squeezing, 等), gem crystals can regularly crack along a specific crystal direction to form a smoother plane. The property is called cleavage. These cracked surfaces are called cleavage surfaces. The cleavage surface is related to the atomic structure of mineral crystals, 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 […]
