But the truth is, the most expensive gem in the world isn’t just dazzling—it’s a symbol of status, history, and sometimes, mystery.
Whether you’re a seasoned jewelry collector or simply captivated by the sparkle of luxury, this deep dive into the planet’s priciest gem is your VIP pass to the glittering world of ultra-rare treasures.
From royal crowns to red carpet showstoppers, gemstones have always carried more than just beauty—they represent power, rarity, and timeless elegance. But what truly makes a gem the most expensive?
In this article, we’ll uncover what qualifies a gem for the record books, reveal the current titleholder of the most expensive gem in the world, and explore other jaw-dropping stones that come close. Along the way, we’ll share expert insights, jaw-dropping price tags, and what you should know before investing in rare stones.
Spoiler alert: It’s not just about size.
As of now, the reigning champion of gemstone luxury is the Pink Star Diamond—a breathtaking 59.60-carat fancy vivid pink diamond that sold at Sotheby’s for a mind-blowing $71.2 million.
Carat weight: 59.60
Color grade: Fancy Vivid Pink (extremely rare)
Price sold: $71.2 million
Auction: Sotheby’s Hong Kong, 2017
Buyer: Chow Tai Fook Enterprises
What sets the Pink Star apart isn’t just its size, but its perfect combination of color intensity, clarity, and flawless cut. In the realm of diamonds, that trifecta is like striking gold—except way, way more valuable.
You might be wondering: why do some gems sell for millions while others cost just a few hundred dollars? Great question.
Here are the key factors that influence a gem’s value:
The rarer the gem, the higher the price. Some gemstones form under particular geological conditions and are found in only one location on Earth.
Especially for diamonds and colored stones, color saturation and the absence of visible inclusions play a significant role.
Size does matter—but only when combined with other quality factors.
A masterfully cut gem maximizes brilliance, sparkle, and visual appeal.
Gems with known and prestigious origins (like Kashmir sapphires or Burmese rubies) often carry higher value.
While the Pink Star holds the top spot, it's not the only jaw-dropping gemstone to make headlines. Let’s look at a few other elite stones that have stunned collectors, celebrities, and gemologists alike.
Type: Fancy Vivid Blue Diamond
Carats: 12.03
Price: $48.4 million
Fun fact: Purchased for a child—talk about a birthday gift!
Type: Burmese Ruby
Carats: 25.59
Price: $30.4 million
Notable for: Being the most expensive ruby ever sold
Type: Blue Diamond
Carats: 14.62
Price: $57.5 million
Sold at: Christie’s Geneva
Each of these stones is prized not only for its size but also for its color saturation, clarity, and rarity—proving that true value lies in the details.
Let’s break it down. The odds of finding a fancy, vivid pink diamond like the Pink Star? Less than 0.01% of all mined diamonds. Some rare gemstones, like painite, are so scarce that fewer than a few dozen known specimens exist globally.
Only 1 in 10,000 diamonds qualifies as “fancy color”
Jadeite, another ultra-valuable gem, can reach $3 million per carat
Red diamonds are considered the rarest of all colored diamonds
When rarity meets demand, prices can skyrocket—and collectors are willing to pay a premium.
Dreaming of owning a rare gem or simply curious about starting a collection? Here's what expert collectors and gemologists recommend:
Always request a GIA certificate or equivalent when buying high-value stones
Ask about origin, treatment history, and ethical sourcing
Work with reputable dealers or auction houses
Use padded, climate-controlled jewelry boxes
Avoid exposing rare stones to harsh chemicals or sunlight
For ultra-valuable gems, consider vault storage and insurance
Rare gems can appreciate, especially those with verified provenance. If you're investing, treat it like fine art—with patience and passion.
Even in our modern, tech-driven world, there’s something ancient and primal about the allure of gemstones. These natural wonders formed over millions of years—and now rest on crowns, red carpets, or behind glass cases at the Smithsonian.
And guess what? You don’t need to spend millions to enjoy their beauty. Brands like Ana Luisa offer thoughtfully crafted jewelry using sustainable materials that look stunning and won’t break the bank.
The most expensive gem in the world may have a price tag of over $70 million, but its true value lies in its story—how it formed, where it came from, and what it represents to the person who owns it.
Whether you're collecting investment-grade stones or simply appreciating the shimmer of your favorite necklace, remember this: the magic of gemstones isn’t just about the price—it’s about how they make you feel.
So go ahead—admire the Pink Star. But also treasure that simple pendant that brings you joy every time you wear it.
You might not be bidding on the Pink Star anytime soon, but that doesn’t mean you can’t bring a little luxury into your everyday life. Explore brands like Ana Luisa for beautiful, ethically sourced jewelry that delivers elegance without the eye-watering price.
Because sparkle, after all, should be for everyone. 💎
