What Is More Expensive Than Diamond? Rarer Gems Ranked
Several gemstones are more expensive than diamond once carat weight, rarity and quality are compared side by side. Fancy colored diamonds in red, pink and blue sit at the top, often trading for hundreds of thousands of dollars a carat, well above the roughly $5,000 to $15,000 a carat a fine colorless diamond commands as of September 2026. Burmese rubies with a pure red hue can cost even more than many fancy diamonds, and lesser-known stones such as painite, musgravite and jadeite regularly sell for tens of thousands of dollars a carat despite almost no public recognition. The pattern holds across every example below: a gem that is harder to find in gem quality tends to outprice a diamond of similar size and clarity.
What Is More Expensive than a Diamond, Ranked by Price
Red, pink and blue diamonds top the list of stones worth more than a standard colorless diamond, followed closely by fine rubies, Kashmir sapphires and Colombian emeralds. Below those sit a handful of gems most shoppers have never heard of, including painite, musgravite, jadeite and alexandrite, several of which pass $50,000 a carat at the high end. The table below lines up typical price-per-carat ranges so the gap is easy to see.
| Gemstone | Price per Carat (Low) | Price per Carat (High) | More Expensive than Diamond |
|---|---|---|---|
| Colorless diamond | $5,000 | $15,000 | Baseline |
| Yellow diamond | $3,000 | $16,000 | Sometimes |
| Ruby, Burmese | $1,000 | $1,000,000+ | Yes |
| Kashmir sapphire | €50,000 | €150,000 | Yes |
| Colombian emerald | €10,000 | €80,000 | Yes |
| Pink diamond | $10,000 | $700,000+ | Yes |
| Painite | $50,000 | $60,000 | Yes |
| Musgravite | $6,000 | $100,000+ | Yes |
| Taaffeite | $1,500 | $35,000+ | Yes |
| Alexandrite | $10,000 | $70,000 | Yes |
| Blue diamond | $200,000 | $3,930,000 | Yes |
| Red diamond | $300,000 | $1,000,000+ | Yes |
| Jadeite, imperial | $20,000 | $3,000,000 | Yes |
European gem dealers commonly quote Kashmir sapphire and Colombian emerald prices in euros rather than dollars. Converted at typical exchange rates, the ranges still land far above the diamond baseline shown in the table.
How Much More Do Fancy Colored Diamonds Cost than White Diamonds
Fancy colored diamonds cost several times to several hundred times more than a comparable white diamond, and the premium grows with how rare the color is. Red is the rarest and most expensive diamond color, followed by pink, blue and then yellow, which is the least expensive of the four.
Red Diamonds
Red diamonds are the most expensive diamond color, selling for more than $1 million a carat on average. Only 20 to 30 natural red diamonds are known to exist worldwide, and the 2020 closure of Australia’s Argyle mine, once the source of most of the world’s pink and red diamonds, tightened supply further and pushed prices higher.
Pink Diamonds
Natural pink diamonds range from about $10,000 a carat for lower grades to more than $700,000 a carat for the finest stones. The 59.6-carat Pink Star sold in 2017 for a price that worked out to roughly $1.19 million a carat, showing how far a top-grade pink stone can climb above that baseline.
Blue Diamonds
Blue diamonds run around $200,000 a carat for a typical 1-carat stone, and the record holder sold for $3.93 million a carat. The Aurora Green diamond, a fancy vivid green stone, sold for $3.3 million a carat in 2016, a reminder that vivid green and blue diamonds trade in the same rarefied territory as the finest rubies.
Yellow Diamonds
Yellow diamonds are the least expensive of the fancy colors, priced from about $3,000 to $5,000 a carat for good clarity and up to $8,000 to $16,000 a carat for a fancy vivid grade. Even at that lower end, a yellow diamond still sits above a mid-range colorless diamond, since color alone adds value that clarity cannot match.
Is a Ruby More Expensive than a Diamond
A ruby can be more expensive than a diamond, though it depends on the ruby’s origin, treatment and color rather than being a fixed rule. An untreated Burmese ruby with a pure pigeon blood red color regularly outprices a diamond of the same size, while a lower-grade or heavily treated ruby usually costs less.
The clearest example is the Sunrise Ruby, a 25.59-carat Burmese stone that sold in 2015 for about 28 million euros, a price that worked out to more than 1 million euros a carat. That figure rivals or beats the per-carat price of many fancy colored diamonds, though it still falls short of the very best red and blue diamonds on record.
Color carries more weight in a ruby’s price than it does in a diamond’s. Diamond pricing leans on the four Cs, color, clarity, cut and carat, weighted fairly evenly, while a ruby’s exact shade of red often matters more than its clarity.
Untreated rubies also command a steep premium over heat-treated stones, since heat treatment is common in the trade and buyers pay extra for a natural, unaltered stone. High-quality specimens without treatment can run from roughly $1,000 to more than $15,000 a carat, and exceptional untreated Burmese stones go well beyond that range.
Not every ruby beats every diamond, though; a fancy red or vivid blue diamond, or a top-grade pink diamond, can still outprice even a fine ruby. Rarity decides the outcome case by case rather than one gem category always winning.
Do Sapphires and Emeralds Cost More than Diamonds
Fine sapphires and emeralds cost more per carat than a standard diamond, and in the top qualities they can run ten to 100 times higher. Both stones owe their price to a distinctive look tied to one small mining region rather than size alone.
Kashmir Sapphire
Kashmir sapphire prices range from about 50,000 to 150,000 euros a carat. The stones are prized for a velvety, cornflower-blue color that gemologists say has never been reliably reproduced by any other sapphire source, which is why buyers pay a premium for a confirmed Kashmir origin.
Colombian Emerald
Colombian emerald prices range from about 10,000 to 80,000 euros a carat, with the highest premiums going to untreated Muzo Green stones. Muzo, one of Colombia’s oldest emerald mines, produces a saturated green color that collectors rank above emeralds from other origins, and that reputation alone adds to the price.
Which Ultra-Rare Gems Beat Diamond Prices
Five lesser-known gems beat diamond prices at their high end: painite, musgravite, taaffeite, jadeite and alexandrite, even though most jewelry shoppers have never encountered any of them. Their value comes almost entirely from scarcity rather than brand recognition.
Painite
Painite costs between $50,000 and $60,000 a carat. It was once considered the rarest gem on Earth, with only two crystals known to exist as of 1950, and its deep red-orange color combined with that history keeps prices high even now that more material has been found.
Musgravite
Musgravite runs from about $6,000 to $40,000 a carat for verified faceted stones, though top-quality specimens have reportedly sold above $100,000 a carat. Sources disagree on where the ceiling sits, and the gap likely comes down to how strictly a seller defines top quality and how the stone was certified; treat any musgravite quote above $40,000 a carat as tied to an exceptional, certified stone rather than the norm. The gem was only discovered in 1967, and an estimated few hundred carats exist worldwide.
Taaffeite
Taaffeite prices span roughly $1,500 to more than $35,000 a carat depending on color intensity and clarity. Pale or lightly colored stones sit at the low end, near $1,500 to $2,500 a carat, while a deeply saturated, gem-quality taaffeite can reach the top of that range.
Jadeite
Imperial green jadeite costs $20,000 to $3 million a carat, a wider range than any other gem on this list. A jadeite necklace weighing 27 carats sold for $27 million in 2014, and Myanmar’s limited deposits combined with deep cultural significance in China keep demand well ahead of supply.
Alexandrite
Alexandrite runs from about $10,000 to $70,000 a carat. Its defining trait is a color shift from green in daylight to red under incandescent light, and that effect combined with limited Russian deposits makes a fine alexandrite rarer than many lab-grown diamonds of comparable size.
What Makes a Gemstone Cost More than a Diamond
Rarity is the single biggest reason a gemstone costs more than a diamond, but origin, treatment history and color all shape the final price too. A stone that combines all four factors, rare, natural, well colored and from a recognized source, commands the steepest premium.
Origin and certification matter because a lab report confirming a stone’s source, such as Kashmir for a sapphire or Muzo for an emerald, can double or triple its value compared with an identical-looking stone from a less prestigious source. Buyers are effectively paying for the paperwork as much as the mineral.
Treatment status works the same way. Nearly all rubies and many sapphires on the market have been heat-treated to improve color and clarity, and that treatment is standard enough that it barely affects price. An untreated stone with the same visual quality, by contrast, is unusual enough to justify a price several times higher.
Diamond buyers weigh color, clarity, cut and carat close to equally, but for rubies, sapphires and emeralds, color usually outweighs the other three combined. A ruby with a slightly better red, or a sapphire with a truer blue, can be worth several times more than a stone that is otherwise identical.
Finite supply closes the loop. Every gem on this list comes from a small number of deposits rather than dozens spread across continents, so new material cannot easily catch up with demand the way it sometimes can for diamonds, which are mined more broadly worldwide.
Shoppers who type what’s better than diamond into a search bar are usually asking about rarity and long-term value, not just sticker price, and the two do not always point to the same stone.
What Would a 2-Carat Ruby Cost Compared to a Diamond
A 2-carat fine untreated ruby priced at even $15,000 a carat, the low end for high-quality specimens, would cost about $30,000 for the pair of carats alone, in line with a 2-carat colorless diamond at the low end of the $5,000 to $15,000 baseline. Move up to a museum-grade stone and the gap turns enormous.
Take the Sunrise Ruby’s roughly 1 million euro per carat price and apply it to a hypothetical 2-carat stone of the same quality: the stone alone would run about 2 million euros, several times what even a fine 2-carat colorless diamond costs at $15,000 a carat, or $30,000 total.
Apply the Pink Star’s per-carat result of about $1.19 million to the same 2-carat hypothetical and the total climbs to roughly $2.38 million, more than 79 times the $30,000 diamond figure. Real stones of that size and quality rarely reach the open market, since so few exist, but the math shows why a small colored stone can outprice a diamond many times its size.
Frequently Asked Questions
What Is the Rarest Gemstone in the World?
Painite held the record as the rarest gemstone for decades, with only two crystals known by 1950. Musgravite, discovered in 1967, is now considered rarer still, with an estimated few hundred carats known to exist worldwide. Both remain far scarcer than diamond, which is mined by the ton every year.
Is a Sapphire More Expensive than a Diamond?
A sapphire is not automatically more expensive than a diamond, since ordinary blue sapphires often sell for a few hundred to a few thousand dollars a carat. Kashmir origin changes that math completely, commanding 50,000 to 150,000 euros a carat because of a rare velvety color and finite historic supply.
What Is the Most Expensive Gem per Carat?
Blue and red diamonds hold the highest confirmed per-carat prices, with the record blue diamond selling for $3.93 million a carat. Fine untreated Burmese rubies and top pink diamonds are not far behind, both capable of crossing $1 million a carat for an exceptional stone.
Are Lab-Grown Diamonds Cheaper than the Natural Stones on This List?
Yes. A lab-grown blue diamond has sold for around $8,500 a carat, compared with roughly $200,000 a carat for a natural blue diamond of similar grade. None of the ultra-rare colored gems on this list, such as painite or musgravite, have a widely available lab-grown equivalent yet.
Does a Bigger Carat Weight Always Mean a Higher Price?
Not proportionally. Price per carat tends to rise faster than carat weight for rare gems, so a 2-carat stone often costs far more than twice a 1-carat stone of the same quality. That effect is strongest in the rarest categories, such as red diamonds and untreated Burmese rubies, where a large, fine stone almost never comes to market.
