Whether you’re interested in buying or selling jewelry at a pawn shop, you might want to know more about which gemstones are worth the most money beyond the familiar options like emeralds and rubies. In addition to white diamonds, which have a value of up to $15,000 per carat, there are several other valuable gemstones you might encounter. Here are the world’s most precious stones.

4 Valuable Gemstones 

1. Taaffeite 

Though lesser-known and extremely rare, taaffeite is one of the most expensive minerals on the market. Originating in the alluvial deposits of Tanzania and Sri Lanka, this gemstone features a gorgeous double refraction effect and sells for approximately $35,000 per carat. 

2. Red Diamond

There are only about 30 red diamonds in the world, which makes them rare and highly valuable. This stone’s red coloration is the result of crystal lattice deformation caused by volcanic eruptions. Red diamonds may cost upwards of $1,000,000 per carat. 

3. Jadeite 

Jadeite is a vivid, pure, and rare version of jade that is widely sought after on the gemstone market. Imperial jade, a semi-transparent form of the stone, represents status and prestige in Chinese culture. In its purest grades, jadeite can be worth as much as $3,000,000 per carat.

4. Blue Diamond

When it comes to precious gemstones, blue diamonds are legendary. Their blue color stems from traces of boron in the crystalline structure. These diamonds are among the most expensive in the world and are valued at nearly $4,000,000 per carat.
