Conditions for gem fire 18ct rose gold bangle

The strength of dispersion of different gemstones is different. It is usually expressed by the difference between the refractive index measured by red light at 686.7nm and purple light (460.8nm 1), and is called dispersion value. En général, the dispersion value greater than 0.03 is called strong dispersion. Colorless or light-colored gems with strong dispersion can sparkle with colorful colors after processing. This color is calledfire colorin gemology, such as diamonds and zircons.

Fire color is one of the precious properties of gems. It makes the gems look bright and adds a lot of beauty to the gems. For gems to appear fire, they must meet the following conditions:

The gem itself should have a high dispersion value. The higher the dispersion value of a gem, the more obvious its fire. Diamonds have a high dispersion value, so the fire is obvious. Any material used to imitate diamonds should have a high dispersion value.

The right cut. In addition to the high dispersion value, gems should also be cut and polished correctly according to a certain style to fully reflect the brilliance of gems. This is the same as the principle that prisms can exhibit dispersion, but flat glass cannot exhibit dispersion. The cut and polished styles of diamonds are carefully designed by people according to the nature of the diamonds, so if the diamonds are processed strictly in accordance with this style, the diamonds can fully display a good fire.

Gemstones that produce fire are generally required to be colorless. Because for colored gemstones, even if the dispersion value is high, the fire color produced is concealed by the color of the gemstone itself.

The gemological significance of dispersion is: dispersion is a valuable property that fully shows the beauty of gems. An important basis for the identification of gems, especially for diamonds.
