Emerald - Gem Color 6 - #50C878

Emerald is a gemstone, and a variety of the mineral beryl colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5-8 on the 10-point Mohs scale of mineral hardness. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor.

The word "Emerald" is derived (via Old French: Esmeraude and Middle English: Emeraude), from Vulgar Latin: Esmaralda/Esmaraldus, a variant of Latin Smaragdus, which originated in Greek: (smaragdos; "green gem").

Emeralds, like all colored gemstones, are graded using four basic parameters - the four Cs of Connoisseurship: Color - , Cut, Clarity and Crystal.
