Gemsuite describes emeralds as a gemstone form of a mineral called beryl. A relatively rare stone compared to diamonds, emeralds feature a vibrant green color.
Emeralds form as hexagonal crystals from beryllium aluminum silicate. They can receive their green coloration from either vanadium or chromium.
Some emeralds form inside hydrothermal veins. When these veins of hot liquid from underground magma contain the right elements for emerald production, emerald crystals may grow as the material cools.
Pegmatite deposits can sometimes form emeralds. These deposits resemble hydrothermal veins except that they contain water rather than magma as their liquid medium.
Manufacturers can duplicate the hydrothermal process to make synthetic emeralds. Crystal nutrients dissolved in an acidic solution receive exposure to high pressure and heat, then they move to a cooler chamber to crystallize.
