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. På nuværende tidspunkt, countries around the world agree with the classification of gems […]

I naturen, all materials that have bright colors, krystaller, og glans; 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. Generelt set, unprocessed […]
Indtil videre, mere end 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 […]
Grunden til, at ædelstene kaldes “skatte” er deres smukke farve. Så hvad er den attraktive farve på ædelstene? Hvor kom det fra? Farve er en elektromagnetisk bølge, der kan mærkes af det menneskelige øje med en bestemt bølgelængde. Dens bølgelængdeområde er ca 400-700 nm i det elektromagnetiske spektrum, også kendt som […]
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, orange, gul, grøn, cyan, blå, og lilla. The hue depends on the selective absorption of visible light by the gem. Lysstyrke, also known as brightness or hue, er den […]
The beauty of gems comes first in color. Derudover, transparency and luster are all its charms. Transparency refers to the ability of a gemstone to transmit light. Usually divided into: gennemsigtig, gennemskinnelig, gennemskinnelig, gennemskinnelig, uigennemsigtig. Gennemsigtighed: 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, ridsning eller slibning kaldes dens hårdhed. 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 […]
Elektrisk ledningsevne er en ædelstens evne til at lede elektricitet. Det afhænger i høj grad af typen af kemisk binding. Ædelstene med metalbindinger er stærkt ledende, fordi de har frie elektroner i krystalstrukturen, mens ionbindinger eller kovalente bindinger er svage eller ikke-ledende. Derudover, the conductivity of gems is also related […]
Under påvirkning af ydre kraft (såsom at slå, klemme, osv.), ædelstenskrystaller kan jævnligt revne langs en bestemt krystalretning for at danne et glattere plan. Egenskaben kaldes spaltning. Disse revnede overflader kaldes spaltningsflader. Spaltningsoverfladen er relateret til den atomare struktur af mineralske krystaller, and is usually the weaker […]
Inklusioner i gemologi refererer til tre aspekter: (1) Det faste, flydende og gasformige stoffer inde i ædelstenen kaldes faste stoffer, flydende og gasformige stoffer. (2) Farvezonering og fordeling eller vækstmønster for ædelstene. (3) Brud, spaltning og revner. Tilstedeværelsen af indeslutninger påvirker ofte kvaliteten af ædelstene, but the regular arrangement of […]
