Another precious stone in the same family as Taaffeite, this stone’s color ranges from a brilliant greenish gray to purple. Musgravite was discovered in 1967 in the Musgrave Range of Southern Australia, and for many years there were only eight known specimens.

Recently, small quantities of Musgravite have been located in Greenland, Antarctica, Sri Lanka, Madagascar and Tanzania. Don’t let this new “surplus” fool you, though: this incredibly hard stone is still exceedingly rare, fetching $35,000 – or more – per carat.

Composition: Magnesium, Beryllium, Aluminum, Zinc, Iron, Oxygen

Jadeite may sound like the various semi-precious stones known informally as “jade,” but this incredibly rare gem is many times more valuable. Prized most when it is colored a deep, translucent green, Jadeite is mainly found in limited quantities in Myanmar.

In 1997, Christie’s auction house sold a Jadeite necklace for nearly $10 million. The highest quality “Imperial” Jadeite can sell for millions of dollars per carat when cut and polished. Sadly, many traders have passed off color-treated stones as true Jadeite.

Composition: Sodium, Aluminum, Iron, Silicon, Oxygen

Named for Tsar Alexander II of Russia, this exceedingly rare gemstone was thought to be mined out after the original deposits, found in 1830 in Russia’s Ural Mountains, were nearly exhausted.

Alexandrite is a color-changing gemstone: its hue shifts from red to green depending on the light it’s exposed to.

Recent finds in Brazil, East Africa and Sri Lanka have brought this stone back on the market, but it is still one of the world’s most coveted stones.

Composition: Beryllium, Aluminum, Oxygen
