The Rarest Gemstone in the World

The Rarest Gemstone in the World

The Rarest Gemstone in the Worldにまつわる役立つ知識を詳しく紐解きます。

If you’re thinking, “What about painite?” you’re right to be suspicious. For years, painite held the title of rarest gem, with only two specimens known in the 1950s. Then, geologists found a deposit in Myanmar and, well, supply crashed the hype. Now painite is still crazy rare, but taaffeite edges it out in overall scarcity because of how spread out and tiny the deposits are. It’s like comparing a single snowflake to a snowdrift—both are rare, but one is basically impossible to find again.

There’s also grandidierite, a blue-green dream that’s almost as rare, but it often has inclusions (read: flaws) that lower its value. Taaffeite, on the other hand, boasts a lovely lavender-to-violet hue and a clarity that makes it look like a tiny piece of galaxy. It’s the gem that says, “I’m not trying to impress you, but I will anyway.”

Why You’ll Probably Never Own One (Sorry)

Let’s talk money, because that’s what we all want to know. A decent taaffeite can cost $3,000 to $5,000 per carat—and that’s for a stone that’s often smaller than a grain of rice. A one-carat taaffeite? That’s like finding a collector’s edition Pokémon card in your attic: it exists, but you’d better sell a kidney. And good luck finding one on Etsy; most sales happen through private dealers and auctions.

But here’s the irony: rarity doesn’t always mean beauty. Some of the rarest gems are dull or ugly. Taaffeite happens to be gorgeous, which is why it’s so coveted. It’s like the gemstone world’s version of a limited-edition Birkin bag—except the bag is actually a magical lilac crystal that only 500 people on Earth have ever touched.
