| | Emerald |
 | | From a chemical-mineralogical point of view, emeralds are beryllium-aluminium-silicates with a good hardness of 7_ to 8, and belong, like the light blue aquamarine, the tender pink morganite, the golden heliodor and the pale green beryl, to the large gemstone family of the beryls. |
 | | Emeralds are also cut in many other, mainly classical shapes, but if the raw material contains a large number of inclusions, it may often be cut into a gently rounded cabochon, or into one of the emerald beads which are so popular in India. |
 | | And one more piece of advice on the purchase of an emerald: whilst diamonds generously scintillate their fire in sizes below 1 carat, you should go for larger dimensions when acquiring a coloured gemstone. |
