Answer 1

A. The emerald was dark and no light came through it.

A variety of the mineral beryl that is coloured green by trace amounts of chromium or, sporadically, vanadium is the gemstone emerald. Beryl ranges from 7.5-8 on the Mohs hardness scale. Since emeralds are typically heavily incorporated, their hardness is frequently rated as average. Emerald is a type of cyclosilicate.

The colour of a genuine emerald will be pure green or blue-green. It will either have no backlight with the light or a dim orange-red or green colour. The fluorescence of synthetic emeralds will be dark red in hue. A brown or yellow undertone will be present in an imitation stone.

The majority of us instinctively think of diamonds when considering expensive and rare gemstones, however emeralds are frequently more expensive because they are over 20 times rarer than diamonds.
