Most Expensive Gem In The World

Okay, grab your coffee and sit down. I need to tell you about the most expensive gem on Earth. It’s not a diamond you’d see in a Beyoncé music video. No, this little rock makes your average engagement ring look like a gumball machine prize.

Meet the Pink Star Diamond

Let’s talk numbers, because they’re insane. The Pink Star diamond sold for over $71 million in 2017. Yes, you read that right. That’s more than most people will earn in a thousand lifetimes—and that’s not even factoring in inflation.

It weighs 59.6 carats. That’s about the size of a jumbo marshmallow, but infinitely less squishy. And it’s a fancy vivid pink, which is basically the gem world’s version of a unicorn sneezing.

Why is it so ridiculously expensive?

First of all, pink diamonds are rare. Like, “find a needle in a haystack” rare. Most diamonds are clear or slightly yellow. A deep, vibrant pink? That’s nature playing favorites. This particular stone came from a mine in South Africa, and it took 20 months just to polish it.

Oh, and it’s also a Type IIa diamond. That means it has almost no impurities. Chemically, it’s as pure as your grandma’s soul. But let’s be honest—the price tag is pure insanity. You could buy a private island with this gem. Or a small fleet of luxury cars.

The runner-up: The Blue Moon of Josephine

Don’t feel too bad for the Pink Star, though. It has a pretty tough competitor. The Blue Moon of Josephine sold for $48 million in 2015. That’s a 12-carat blue diamond. Blue diamonds get their color from boron trapped inside the crystal. Basically, it’s a fancy science trick that costs more than your house.

This one was bought by a Hong Kong billionaire. He named it after his daughter. Because, you know, when you have that kind of cash, you don’t buy a car—you buy a rock and call it a family heirloom.

What about the Hope Diamond?

You’ve probably heard of the Hope Diamond, right? That big blue one in the Smithsonian? It’s famous, but it’s not the most expensive. Why? Because it’s been in a museum for decades. You can’t actually buy it. And honestly, it’s cursed. People died, ships sank, bad vibes everywhere. So maybe that’s why it’s cheaper—the price tag includes the psycho baggage.

Other contenders you’ve never heard of

There’s the Oppenheimer Blue Diamond, which sold for $57 million. Then you have the Graff Pink at $46 million. Honestly, it’s like a game of “who has the biggest wallet?” And the answer is always “some guy in Dubai or Hong Kong.” These aren’t gems you buy for a girlfriend. These are gems you buy to show you’ve truly run out of ideas for tax write-offs.

Wait, are there any gems more expensive per carat?

Oh, absolutely. Sometimes the price per carat is the real punchline. The Pink Star costs about $1.2 million per carat. But there’s a tiny, 0.59-carat red diamond called the Moussaieff Red that’s worth $20 million in total. Do the math—that’s over $33 million per carat. That’s more per gram than a rocket ship made of gold. Red diamonds are so rare that most jewelers will never see one in their career. They’re like the Loch Ness Monster of gems, but with better marketing.

Can you top this? The Crimson Flame

Another monster is the Crimson Flame, a 15-carat red diamond that’s basically priceless. For sale? Maybe. But good luck getting a quote. The owner probably answers the phone with, “Do you have a spare $50 million? No? Then stop breathing my air.”

Rarest Diamond In The World

Here’s the kicker: most of these stones sit in vaults. They’re rarely worn. Someone owns them, but they’re locked up for 364 days a year. It’s like buying a Ferrari and letting it sit in a garage—except this Ferrari is a pink rock that glows, and it’s worth more than your entire zip code.

So, what’s the crown jewel?

If you want the absolute most expensive single gem ever, still the Pink Star wins. It holds the auction record. But if you ask gem nerds, they might argue for the CTF Pink Star (its official name) because it’s been reappraised higher. Honestly, it’s like arguing over who’s the better Beatle—everyone has an opinion, but the numbers don’t lie.

Think about it: you could buy a small country, fund a space mission, or pay off your student loans ten thousand times over. Instead, someone chose to buy a shiny stone. Is that stupid? Maybe. Is it kind of awesome? Yes. Because at that level of money, nothing makes sense anymore. It’s just sparkle and ego.

Final thought

If you’re ever in a jewelry store and someone whispers, “We have a pink diamond,” don’t even ask the price. Just nod slowly, back away, and thank the universe that your biggest expense today is probably a latte. The most expensive gem in the world is a flex so absurd that even wizards would blush. And honestly? I’m just glad I’m not the one insuring it.
