Indigenous rocks make possible the expansion environment for aquamarine formation. The dimension of the crystal is in relation to the cooling rate. Huge crystals are produced while the cooling is very sluggish. These gemstones get shaped in nature under precise aggressive geologic conditions. When the mineral-rich aggressive magma flowed under into the rock layers of mountain range. As it gets chilled, the magma fluid gets intent in to cavities of mineral-saturated fluid that gets heated to a very elevated temperature 1,112 F.

Physical Properties :

The chemical method for aquamarine, along with all other beryls, is Be3Al2(SiO3)6. The color of the stone comes from trace amounts of iron which have become embedded in the hexagonal crystalline formation of the stone.
