The Top 10 Rarest Gemstones in the World
For over 40 years, we’ve been searching the world for the rarest gemstones. Rarity has many elements. According to American Gem Lab, out of 3000 registered mineral species and varieties, less than 500 are known to be suitable to be cut into a gemstone.
However, not all gemstones marketed as rare are actually that. Rarity and price don’t always go hand in hand either. A gemstone’s rarity must not be confused with value. Something has more value when others are willing to pay for it in the open market. Diamonds are a good example. Extremely expensive but not rare.
Our list includes many gemstones that are not commonly found in jewelry because of how hard they are to be faceted and found. Pricing of rare gemstones will always be dictated by demand. The average person is completely unaware of these esoteric gemstones making demand less than it should be.
Collectors, and museum curators are usually knowledgeable when it comes to rarity. Size and clarity are among the elements of Rarity, that can have an exponential effect on any stone’s ranking. We limited consideration for these two elements in our ranking system.
Here is our updated list of the World’s 10 Rarest Gemstones.
