Olivine is a magnesium-iron silicate mineral, belonging to the orthorhombic crystal system. Współczynnik załamania światła wynosi 1.654-1.690, and the birefringence difference is quite high as 0.036. From the table of the gemstone, the ridgelines of the bottom facet become overlapping The double shadow is because of the high birefringence difference, współczynnik dyspersji wynosi 0.020, [...]
Before the development of synthetic technology, the scientific name of hyacinth zircon is the closest natural gemstone to diamond, so zircon can be said to be the earliest natural substitute for diamond, because it has a fairly high refractive index and its dispersion rate is close to that of natural diamonds. W porównaniu z diamentami, . [...]

According to the characteristics of feldspar, it can be divided into Orthoclase and Plagioclase. Moonstone is a kind of orthoclase, with a refractive index of 1.518-1.526, różnica dwójłomności 0.005, A [...]
Calcite is a calcium-containing carbonate mineral. It is a very important mineral in the earth's crust. It is often used as a teaching material to explain the characteristics of gems, but it is rarely used as jewelry because it has a very high birefringence difference and a perfect solution. Reason, although other gems also have [...]

Siła dyspersji różnych kamieni szlachetnych jest różna. Zwykle wyraża się go różnicą pomiędzy współczynnikiem załamania światła mierzonym w świetle czerwonym o długości fali 686,7 nm i w świetle fioletowym (460.8nm 1), i nazywa się wartością dyspersji. Ogólnie, wartość dyspersji większa niż 0.03 nazywa się silną dyspersją. Colorless or light-colored gems with strong dispersion can [...]
1. Helps identify gem species There are special inclusions in some gems, a rodzaje klejnotów można określić, badając te inkluzje.
