EMERALD IS A VARIETY OF THE MINERAL BERYL, COLORED GREEN BY TRACE AMOUNTS OF CHROMIUM AND SOMETIMES VANADIUM. BERYL HAS A HARDNEDD OF 7.5 – 8 ON THE 10 POINT MOHS SCALE OF HARDNESS. MOST EMERALDS ARE HIGH INCLUDED, SO THE BRIGHTNESS (RESISTANCE TO BREAKAGE) IS CLASSIFIED AS GENRALLY POOR. THE ORIGIN OF THE WORD “EMERALD” IS SAID TO BE A SANSKRIT WORK MEANING “GREEN”.
