Red Diamond of Rio Tinto

Red Diamonds: Elegance and Rarity of Expensive Jewelry

Natural red diamonds stand as the pinnacle of rarity among colored diamonds. These special gems have a beautiful color, which makes them very valuable in gemology. Some of them are Type IIa with a special crystal structure. The Gemological Institute of America (GIA) says pink diamonds are scarce and unique in the world of fancy-colored diamonds.


Gem certifiers have only certified fewer than twenty of these stones, distinguishing them from other colored gems that may be larger. The record for these gems does not surpass 5.11 carats, underscoring their exceptional rarity. This scarcity is a hallmark of why these diamonds remain so coveted and valuable.

The most notable among these is the Moussaieff Red, which comes from Brazil and was discovered in the 1990s. Originally named the Red Shield, this 5.11-carat diamond was once 13.90 carats. Now worth around $8 million. Such figures reflect not just the stone’s market worth but its iconic status among gem enthusiasts.


Another significant piece is the 5.05-carat emerald-cut stone known simply as Red Diamond. Originating from South Africa in 1927, its current location remains a mystery, adding to the lore and allure surrounding these exquisite stones. The narrative of such gems fuels the fascination and high regard held by collectors and aficionados alike.


Mistaken at one time for a garnet, the 5.03-carat round brilliant De Young Red is the third-largest red diamond in existence. The diamond, named after its previous owner – Boston jeweler Sidney De Young – is now part of the National Gem and Mineral Collection at the Smithsonian Institution.
