The most valuable color of the diamond is also red! However, you should know that the vivid color of diamonds can make them valuable as well. Besides red, pink, and blue diamond colors have also been sold for record-breaking prices and exist as some of the rarest and most expensive gemstones in the world. Some of the most valuable pink diamonds are CTF Pink Star, Graff Pink, the Sakura Pink diamond, etc. and the most valuable blue diamonds are Blue Moon of Josephine, the DeBeers Blue, and the Oppenheimer Blue Diamond. 

When it comes to red diamonds, it’s very rare to find a red diamond of a bigger size than other colored diamonds. Most valuable red diamonds come in 5 carats and the majority of red diamonds weigh somewhere under a carat! Here are some of the most valuable red diamonds around the world:

#1 The Moussaieff Red Diamond

The Moussaieff red diamond is the largest red stone ever graded by the GIA, the rarest of all diamond colors, and comes in a triangular brilliant cut. It’s weight is 5.11 carats and it’s the largest red diamond to exist in the entire world! The stone was found in Brazil during a manual digging operation in 1989. It was immediately purchased by William Goldberg of the William Goldberg Diamond Corp, who had to take several trips to complete the purchase. He took the 13 carats of raw stone and cut it to 5.11 carats with a radiant cut! Known as the Red Shield diamond at the time, the coveted stone attracted another renowned jeweler of the time – Shlomo Moussaieff. 

Shlomo Moussaieff of the Moussaieff Jewelers was the sole heir of his father’s gemstone business and decided to purchase the red diamond from Goldberg. The purchase happened somewhere around 2001 or 2002 after which he renamed the diamond The Moussaieff Red Diamond in honor of his family’s legacy. The public got a glimpse of the remarkable gemstone as part of the Smithsonian Institution’s “The Splendor of Diamonds” exhibit where it was displayed alongside other valuable diamonds like the De Beers Millenium Star (a 203-carat internally and externally flawless pear-shaped colorless diamond) and the Heart of Eternity diamond (a 27.64 carats fancy blue vivid diamond). 

#2 The Kazanjian Red Diamond

The Kazanjian Red Diamond weighs just a little over 5 carats and is owned by the Kazanjian brothers, a jewelry company in Beverly Hills. The diamond has an interesting history. It was first found in a diamond rush in South Africa and was a 35-carat unpolished stone. It was sent to a jeweler in Amsterdam who were initially skeptical of its worth. They later cut and polished the stone to 5 carats and were mesmerized by the appearance, describing it looking as a “drop of blood” when held near a candle. They wanted to sell it to Tiffany & Co. but couldn’t agree on the price. It was then kept safely in Amsterdam until the Nazis confiscated the diamond. 

After the war was over, it passed on to several buyers, including Ernest Oppenheimer, before being bought by a private collector. After remaining under wraps for a few years, the diamond was bought by the Kazanjian brothers who purchased it from an unknown buyer in Asia. Previously known as the “red diamond”, the stone was renamed and remains unmounted to this day. It is an emerald-cut red diamond and has a certain charm that’s hard to ignore. 

#3 The DeYoung Red Diamond

The DeYoung red diamond is the third-largest red diamond in the world and it’s owner didn’t even know it was a diamond when he brought it! Yes, the 5.03 carats red diamond was mistaken to be a common yet extraordinary gemstone by its owner Sydney DeYoung. The jeweler bought it at a flea market and thought it was a garnet. It was only later that he realized there was something extraordinary about the stone as it was almost inclusion-free, looked almost flawless, and had a certain shine to it! He took the stone for gemological testing and was shocked by the results. The gemstone was a 5.03 carat VS2 fancy brownish-red diamond and was much more valuable than the price he paid! 

After DeYoung’s passing in 1986, the diamond was donated to the Smithsonian Institution, as directed by his will. Today, you can find this diamond on display in the museum along with some of the other valuable and rare diamonds in the world. Owing to its rarity, it’s placed in a prominent area of the museum and is the only red diamond in the world that is on display in the museum! 

#4 The Graff Purplish-Red Diamond

Auctioned in 2020 at Christie’s and sold for a whopping 2.77 million USD, the Graff Purpish-red diamond was unnamed before being bought by the famous English Jeweler, Laurence Graff, who is the founder of well-known Graff Diamonds. He has brought many valuable colored diamonds before and named them after him and his company. These include the Graff Pink Supreme, the Graff Pink Yellow, and the Graff Imperial Blue diamond! The diamond is gorgeous and is known for its unique color. 

The Graff Purplish-Red diamond has a unique defect in its lattice and is one of the rare structurally imperfect Type IIa diamonds. Type IIa diamonds are a specific classification within the diamond grading system. They are known for their exceptional purity and structural composition. The diamond is now set into a ring by Graff and is a part of his gemstone collection. Not much is known about its history or origins, and it’s one of the popular and valuable diamonds that has remained almost non-existent throughout the history. Some experts do claim that the diamond might have been found in South Africa or Brazil. 

 #5 The Hancock Red Diamond 

The Hancock Red Diamond is a 0.95 carats brilliant-cut vivid red gemstone with its origins in Brazil and was first bought by William Hancock, a Montana rancher who loved collecting colored gemstones, in 1956 for $13,500. At the time very few people even knew about colored diamonds and there were also very limited ways to determine if the diamond was real or not, hence the low price he paid for the diamond. Hancock brought the diamond from dealer Arnold Baron. Details on how Arnold Baron received the diamond remain unknown, and so does the original carat weight of the diamond. 

He owned the stone for around 30 years before it was sold at Christie’s auction for a record-breaking price of $880,000 per carat and made a profit of 6500%. It was the highest-selling diamond per carat at the time and held the record for 20 years. It was sold after the death of William Hancock and was sold by his family as they were in desperate need of cash. It’s pre-sale estimate was 150,000 USD per carat, but it far exceeded the estimate. Besides the red diamond from Hancock’s collection, a purple-pink diamond and a reddish-purple diamond was also sold from his collection for hefty amounts. 

How To Determine The Originality Of The Diamond?

What Diamond Color Is The Rarest & Most Expensive

Determining the originality or authenticity of a diamond involves assessing its characteristics, certifications, and the credibility of the seller. Here are some key steps to help you determine the originality of a diamond.

#1 Certification:

Start by checking if the diamond comes with a grading report from a reputable gemological laboratory. The most well-known and respected diamond grading laboratories include the Gemological Institute of America (GIA), the American Gem Society (AGS), and the International Gemological Institute (IGI). Review the certification to ensure it matches the diamond you are examining.

#2 Verify the Certification:

Take note of the unique certification number on the diamond’s grading report. Contact the issuing laboratory and provide them with the details to verify the authenticity of the diamond and the accuracy of the grading report.

#3 Inspect the Diamond: 

Examine the diamond closely using a jeweler’s loupe or microscope to identify any visible inclusions, blemishes, or other unique characteristics. Look for natural imperfections that are typically present in genuine diamonds. If the diamond appears too flawless or perfect, it could be a sign of a synthetic or lab-grown diamond.

#4 Consider the 4Cs:

Evaluate the diamond’s cut, color, clarity, and carat weight. Genuine diamonds exhibit a range of characteristics within these factors. Familiarize yourself with the expected range of values for each category based on the grading report and industry standards.

#5 Seek Professional Appraisal:

If you are uncertain about the diamond’s authenticity, consider seeking a professional appraisal from a reputable and independent gemologist or certified appraiser. They can provide an unbiased evaluation and assessment of the diamond’s authenticity and value.

#6 Purchase from Reputable Sellers: 

Buy diamonds from trusted and established jewelers or retailers with a solid reputation. Research the seller’s credentials, customer reviews, and any certifications they may possess. Reputable sellers are more likely to provide authentic diamonds with proper documentation.
