The Stone of the Kings
Emeralds, part of the beryl family, are known for their striking green color, which is due to the presence of chromium and vanadium. They have a hardness rating of 7.5 to 8 on the Mohs scale, making them durable yet delicate enough to require careful handling.
Emeralds have been valued for thousands of years, from ancient Egypt, where they symbolized rebirth, to Rome, where they were believed to have soothing properties.
