20 Rarest Gems In the World That Will Shock You With Their Price Tag

Black Opals are from a Different League

The Black Opal flashes a brilliant rainbow of colors and cost $2,355 per carat. With 95% coming from New South Wales, Australia, these gems have supposedly been coveted by kings, emperor, maharajas and sultans throughout history. The black opal is the rarest and most valuable of all the opals, with the Red Fire black opal being the most exotic of this unique type. Definitely way more expensive than a regular opal, it’s still not a bank-breaker.

The Delicate Poudretteite

This lovely soft pink gemstone was first discovered in Quebec, Canada, and costs around $3,000 per carat. Because of its soft nature, the Poudretteite is not suitable for a ring, which would cause more wear and tear to the stone, but is suitable for earrings and pins as long as good care is taken.

The Blueist of Them All

The Benitoite is an electrifying blue stone that is only found in the United States at the San Benito River in San Benito, California. This rare gem glows under UV light and the origin and its fluorescent properties still remain a mystery. The exquisite stone fetches up to $4,000 per carat.

About Those Emeralds

Emeralds come from all over the world, with the largest producer being Columbia. These powerful green gems fetch about $8,000 per carat if they are eye-clean. Eye-clean means free of inclusions to the unaided eye (which is rare with emeralds). Top ones must also be a pure luxuriant green hue and have a high grade of transparency.
