Emerald is a Beryl gemstone, just like Aquamarine and Morganite. It’s well-known for its grass-green colour which it attains from the elements, chrome and vanadium when created underground. Emerald is a gemstone often seen with many inclusions, sometimes in fine patterns. Among others, emerald is mined in Columbia, Zambia, Zimbabwe, Russia, Brazil, Pakistan and Afghanistan. When measuring a gemstone’s hardness, Moh’s Hardness Scale is used. The scale goes from 1-10, where 10 is the hardest – here you would find the diamond, which is the hardest gemstone. Emeralds are often around 7.5 and 8 on Moh’s Hardness Scale.
