Diamonds are supposed to be the rarest of them all, and while there might be some spectacular, expensive, and rare ones, there are some gems that have the diamond beat in value, rarity, price and beauty. You’ve probably never heard of many of these and some are so precious that there are only three known in the entire world.

Tell your soon-to-be-fiancé not to get his hopes up when you say that you have something different in mind when he starts talking diamonds. Get ready — averaging at $46,000 per carat, most of these will truly break the bank!

Tanzanite’s Spellbinding Blue

Supposedly Tanzanite is a thousand times rarer than a diamond. There’s only a limited supply and they’re found exclusively in the foothills of Mount Kilimanjaro. Electric blue and violet, the colors fluctuate due to vanadium ions. This stunning gem was given its name by Tiffany & Co. in honor of Tanzania, where they come from and cost around $1,500 per carat.

Royal Demantoids

This brilliant green gem is electrifying; its color ranges from yellowish-green to true emerald green. Demantoids, a member of the garnet family, are valued at about $2,000 per carat, and were first discovered in the Ural Mountains of West Central Russia in the mid-1800s. They’re especially known for having the brilliance and dispersion of a diamond, rare for a typical garnet, and have been coveted by royal families.


This rare stone was first discovered in Siberia at the end of the 19th century. Jeremejevite is composed of aluminum and borate minerals, with variable fluoride and hydroxide ions. Costing $2,000 per carat, the stone ranges from colorless to sky blue and pale yellow, and is often mistaken for an aquamarine. The highest quality stones are found in Namibia.

Taaffeite Trumps the Diamond in This Case

This gem ranges from red to purple and costs about $2,000 per carat. Taaffeite (pronounced TAR-fight) is over a million times scarcer than the diamond and can be found in Sri Lanka, Southern Tanzania and China.
