Gemstones have captivated humanity for millennia, serving as symbols of wealth, power, and beauty. Among these precious stones, some stand out not only for their rarity and beauty but also for their astronomical value. When discussing the most expensive gemstone in the world, several contenders come to mind, each with a rich history and a price tag that reflects its extraordinary qualities. This article delves into the world of these unparalleled gems, exploring what makes them so valuable, their historical significance, and the factors that contribute to their sky-high prices.
The Concept of Value in Gemstones
Before diving into the specific gemstones, it is essential to understand what makes a gemstone valuable. The value of a gemstone is determined by several factors, commonly referred to as the “Four Cs”: Carat, Cut, Clarity, and Color. Each of these factors plays a crucial role in determining the price of a gemstone.
Carat: The weight of the gemstone is measured in carats, with one carat equivalent to 0.2 grams. Generally, the heavier the stone, the more valuable it is, assuming the other factors are also of high quality.
Cut: The cut of a gemstone refers to how it has been shaped and faceted. A well-cut gemstone will reflect light in a way that enhances its brilliance and color. The quality of the cut can significantly affect the stone’s appearance and value.
Clarity: Clarity refers to the presence or absence of internal flaws (inclusions) or external blemishes in the gemstone. The fewer inclusions and blemishes, the more valuable the stone is.
Color: The color of a gemstone is perhaps the most crucial factor in determining its value. For some gemstones, such as diamonds, the lack of color (being colorless) is highly prized. For others, like emeralds and rubies, rich and vivid colors are more desirable.
In addition to the Four Cs, rarity plays a significant role in a gemstone’s value. A gemstone that is rare or comes from a unique source can command a higher price simply due to its scarcity. Historical significance and provenance can also add to a gemstone’s value, as stones with a storied past or connections to royalty and celebrities are often more desirable.
The Pink Star: The Reigning Champion
When discussing the most expensive gemstone in the world, one name that consistently comes up is the Pink Star. This magnificent diamond holds the record for the highest price ever paid for a gemstone at auction, selling for a staggering $71.2 million in April 2017 at Sotheby’s Hong Kong.
The Pink Star is a 59.60-carat oval mixed-cut pink diamond that is classified as a “Fancy Vivid Pink” by the Gemological Institute of America (GIA). This classification places it in the highest echelon of colored diamonds, where color intensity and purity are paramount. The Pink Star’s vivid pink hue, coupled with its remarkable size and flawless clarity, makes it an unparalleled treasure in the world of gemstones.
The Discovery and Journey of the Pink Star
The Pink Star’s journey began in Africa, where it was discovered in 1999 as a 132.5-carat rough diamond by De Beers, one of the world’s leading diamond companies. The rough stone was meticulously cut and polished over a period of two years by Steinmetz Diamonds, a renowned diamond manufacturer. The result was the breathtaking 59.60-carat gem that would eventually become known as the Pink Star.
The diamond was first unveiled to the public in May 2003 under the name “Steinmetz Pink” in Monaco. It was later renamed the Pink Star and went on to become a highly sought-after gem, making appearances at various exhibitions around the world before finally being auctioned off in 2017.
Why the Pink Star Is So Valuable
Several factors contribute to the Pink Star’s extraordinary value:
Color: The Pink Star’s “Fancy Vivid Pink” color is one of the rarest and most desirable hues in the world of diamonds. Pink diamonds are incredibly rare, with only a tiny fraction of the world’s diamonds exhibiting this color. The intensity and purity of the Pink Star’s color make it particularly valuable.
Size: At 59.60 carats, the Pink Star is the largest internally flawless fancy vivid pink diamond ever graded by the GIA. The combination of its size and color is unparalleled, making it a truly unique gemstone.
Clarity: The Pink Star is classified as internally flawless, meaning it has no inclusions visible under 10x magnification. This level of clarity is exceptionally rare, especially in a diamond of this size and color.
Provenance: The Pink Star’s journey from its discovery in Africa to its auction at Sotheby’s adds to its allure. Its association with De Beers, Steinmetz Diamonds, and its appearances at prestigious exhibitions around the world enhance its historical significance.
Other Contenders for the Title of Most Expensive Gemstone
While the Pink Star holds the record for the highest auction price, several other gemstones are worth mentioning for their extraordinary value and unique qualities.
The Hope Diamond: A Legendary Blue Gem
The Hope Diamond is perhaps the most famous gemstone in the world, known for its deep blue color and storied history. Weighing 45.52 carats, this diamond has a long and fascinating history that dates back to the 17th century.
The Hope Diamond’s deep blue color is due to trace amounts of boron within the stone. Classified as a Fancy Dark Grayish-Blue by the GIA, the Hope Diamond is one of the most recognizable gemstones in the world.
The diamond’s history is as intriguing as its appearance. It was originally part of the French Crown Jewels, known as the “French Blue,” before it was stolen during the French Revolution. The diamond resurfaced in London in 1839 and was eventually purchased by Henry Philip Hope, after whom it is named. The Hope Diamond has since passed through several owners, including Pierre Cartier and Harry Winston, before being donated to the Smithsonian Institution, where it is now on permanent display.
The exact value of the Hope Diamond is difficult to determine, as it is not for sale and has not been auctioned. However, estimates place its value at over $350 million, making it one of the most valuable gemstones in the world.

Another notable contender for the title of most expensive gemstone is the Blue Moon of Josephine, a 12.03-carat Fancy Vivid Blue diamond that sold for $48.4 million in November 2015 at Sotheby’s Geneva. The diamond was purchased by Hong Kong billionaire Joseph Lau, who named it after his daughter, Josephine.
The Blue Moon of Josephine is renowned for its intense blue color, which is one of the rarest hues found in diamonds. The GIA classified it as a Fancy Vivid Blue, the highest grade for blue diamonds. Its flawless clarity and perfect cut add to its value, making it one of the most expensive diamonds ever sold.
The Oppenheimer Blue: A Record-Breaking Blue Diamond
The Oppenheimer Blue, a 14.62-carat Fancy Vivid Blue diamond, set a record in May 2016 when it sold for $57.5 million at Christie’s Geneva. Named after its previous owner, Sir Philip Oppenheimer, the diamond is one of the largest and most vivid blue diamonds ever auctioned.
Like the Blue Moon of Josephine, the Oppenheimer Blue’s value is largely attributed to its color. Blue diamonds are incredibly rare, and those with a vivid hue are even more so. The Oppenheimer Blue’s size, clarity, and historical significance further contribute to its high value.
The Graff Pink: A Rare and Exquisite Pink Diamond
The Graff Pink is another exceptional gemstone that has commanded a high price at auction. This 24.78-carat Fancy Intense Pink diamond was sold for $46 million in November 2010 at Sotheby’s Geneva, making it one of the most expensive diamonds ever sold.
The Graff Pink is classified as a Type IIa diamond, which means it is almost entirely free of impurities and exhibits exceptional transparency. Its intense pink color, combined with its clarity and size, makes it one of the most valuable gemstones in the world.
The Peacock Brooch: A Masterpiece of Colored Diamonds
While diamonds often dominate the list of the most expensive gemstones, other types of precious stones also command high prices. The Peacock Brooch, created by Graff Diamonds, is a stunning example of this. The brooch features a 20.02-carat Fancy Deep Blue diamond as its centerpiece, surrounded by an array of colored diamonds totaling 120.81 carats. The brooch is valued at $100 million, making it one of the most expensive pieces of jewelry ever created.
Factors Influencing the Value of Gemstones
The value of a gemstone is influenced by various factors beyond the Four Cs and rarity. Understanding these factors provides insight into why certain gemstones command such high prices.
Origin: The origin of a gemstone can significantly impact its value. For example, Kashmir sapphires, Burmese rubies, and Colombian emeralds are considered the finest in the world due to their superior color and quality. The origin of a gemstone can add a premium to its price.
Historical Significance: Gemstones with a rich history or connection to famous individuals often command higher prices. The Hope Diamond, for instance, is valued not only for its color and size but also for its storied past.
Cultural and Emotional Value: In some cultures, certain gemstones are associated with specific beliefs or traditions, adding to their value. For example, jade is highly prized in Chinese culture for its symbolic meaning and is often more expensive than other gemstones of similar quality.
Market Demand: The demand for certain gemstones can fluctuate based on trends and economic conditions. For example, pink diamonds have seen a surge in demand in recent years, partly due to their rarity and the closure of the Argyle mine, one of the primary sources of pink diamonds.
Celebrity Influence: Celebrities often have a significant impact on the popularity and value of certain gemstones. For example, the engagement ring given to Kate Middleton by Prince William, which features a blue sapphire, led to a surge in demand for similar stones.
