Here Are the Seven Most Valuable Gems in the World


Alexandrite

Found in Russia, India, Sri Lanka and Tanzania, Alexandrite is very scarce. They are almost always found in one carat sizes or smaller. One carat is worth $15,000 or $70,000 for rarer, larger stones. The Smithsonian Institution owns a 65.08 carat, cushion-cut Alexandrite gemstone worth $4 million.
