Columbian emeralds have been found in archeological digs dating back to pre-Columbian times, from the 1200’s, as artifacts such as crystals set in gold. Prior to the 16th century, Cleopatra’s Egyptian deposits were the only known source of emeralds for Europe and Asia. But after the discovery of large, clear, saturated crystals in Columbia, the Egyptian material was considered to be of only historical significance.
Emeralds, like all beryls, have a hardness of 8 to 8.5 on the Mohs scale, which means they can take a fair amount of abuse and can’t be scratched by most objects. However, because many emeralds have fissures that make them vulnerable to breaking, one should be careful not to smack the stone against something hard.
