Smaragd in Quartz


The name Smaragd is another name for "Emerald" (Émeraude French, Smaragd German, Esmeralda Spanish) comes from the Greek word smaragdos, a name that was given to several gemstone minerals having little in common chemically, but sharing a similar bluish-green colour.
​​​​​​​An emerald is a form of Beryl, a mineral group that includes Aquamarine and Morganite. Emerald's leaf-green colour is partially due to allochromatic coloration from trace amounts of chromium (Cr) and vanadium (V) impurities.
