Beryl in English is derived from Beryllos in the Hitho language. The earliest roots should be derived from the Indian language. There is no relevant record of what this means, so it is not possible to know how the beryl was named. German beryl is derived from beryl from brille, because the earliest spectacle lenses were ground with colorless beryl.
The refractive index of beryl is 1.576-1.600, the refractive index of emeralds is mostly between 1.576 og 1.582, the birefringence difference is 0.005 til 0.009, the dispersion rate is 0.014, and the hardness is between 7.5 og 8, but the toughness is very poor. , So beryl is more fragile than other gems, and it is very small when inlaid and worn.
Beryl also comes in many colors, but in the gem market, emeralds, aquamarine, and morganite are the main ones. The other colors of beryl are mostly collected by gemologists and mineralogists.
Emerald is the most expensive gem among beryls, but it usually contains many inclusions. In the gem world, emeralds have the reputation of “Gem Garden” Jardin, and the inclusions have become emeralds’ characteristics rather than disadvantages. Others The content of beryl is not so obvious. Emerald is colored by containing chromium or vanadium, while aquamarine is caused by iron.
