The 15 Most Expensive Gemstones That Are Not Diamonds

Picture the most valuable gemstone. Many will imagine a stunning brilliant-cut diamond. Others will imagine popular precious gemstones, like rubies or sapphires. Some only focus on carat size. But the list of the most expensive gemstones may surprise you.

What is a gemstone? It’s a mineral that’s valued for its beauty and market value. But not all precious gemstones are expensive.

Featured by some of the best jewelry brands, the most valuable gemstones are stunning. But they also have two things in common. These precious gems are rare. And while many precious gemstones are lab-grown, all of these are natural gemstones.

These rare gemstones have graced the red carpet. They’ve been featured on some of the most expensive shoes of all time.
