Humans have been mining this green variety of beryl for approximately 5000 years.
The green colour of this stone is caused by small amounts of chromium and vanadium. The highest quality emeralds are a deep grass green colour with a bluish cast and can be more valuable than diamonds.
Emerald is the birthstone for May.

Emeralds often contain inclusions, fissures and flaws. As a result, many emeralds are oiled, a treatment that reduces the visibility of inclusions and improves the clarity of the stone.
The emerald cut – a rectangular or square cut with bevelled corners – was developed to show this stone to best advantage. Removing the corners helps protect this brittle stone from breakage.
Caring for your emeralds: Emeralds should only be cleaned with a soft, dry cloth. An ultrasonic cleaner should never be used on emeralds and one should always remove any emerald rings before putting hands in soapy water. Emeralds which are oiled can dry out, so at times the stones will need to be re-oiled.
