Semi-precious gemstones have been used for centuries in healing, energy production and spiritual growth. The stones can be used to heal the mind, body and spirit in a variety of ways. Whatever the need, there is a stone that resonates with the energy to overcome almost any obstacle.
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: σμάραγδος (smaragdos; "green gem").
