What Is the Largest Gem in the World?
The largest raw gem ever taken out of the ground is a topaz that weighed 596 pounds, that’s 1,380,000 carats!
This huge gem was found in Brazil, but is now in the American Museum of Natural History in New York City. Although it’s the largest gem, it’s also a poor quality topaz, so it’s rather dull-looking.
The largest gem of true gem quality, which means it’s good enough to use in jewelry, is an aquamarine found in Brazil in 1910. This giant gem weighed 229 pounds, which equals 520,000 carats!
