Emerald was a cherished gem in ancient times. The ancient Egyptians highly prized emeralds, and Cleopatra was known to have collected them. During her reign, she claimed ownership of all the emerald mines in Egypt. Pliny the Elder, a famous naturalist of Ancient Rome, recommended looking at emeralds as a relief for eye strain. The name of the gem comes from the Ancient Greek “smaragdus”, meaning “green”.
