| The emerald is a type of beryl, like Aquamarine. A stone can only be considered an emerald if it is a vivid green. If the green is pale or yellowish it is merely green beryl. Emeralds have a hardness of 7 1/2 to 8. The crystals are hexagonal. Emeralds are rarely found in sand and gravel. They are more likely to be found in parent rocks. The Spanish conquestors stole large amounts of emeralds from the Incas. They spent years trying to find the mines. The Spanish finally found one in the mid-1500's. More have been found since then. Emeralds are found in Colombia and other parts of the Andes Mtns. |
