Scarcity of Emeralds

Carat for carat, emeralds are one of the rarest gemstones found on earth; even more so than diamonds.

Chemically, emerald is the mineral beryl spiked with specific varieties of impurities, usually vanadium and Chromium. It is interesting to note that beryl is composed in great part of beryllium, which far less common (about 1.5 parts per million in the upper crust) than carbon (carbon is the fourth most prevalent element in the known universe), the foundation of diamond.

Complicating this is the fact that while all emeralds are technically green varieties of the mineral beryl, not all green beryl are emeralds. The infrequent occurrence of gemstone quality material further increases its scarcity.

Near-flawless emeralds of large carat weight are without question one of the most rarest gemstones of all, and such specimens regularly fetch for many times more than a similarly large carat weight diamond.
