Red diamonds are among the rarest and most valuable diamonds in the world. These stunning gems are so scarce that even small red diamonds can command extraordinary prices at auction. In fact, only about 1 carat out of every 10,000 carats mined is a natural fancy-colored diamond, making red diamonds with deeper saturation incredibly valuable and highly sought after.
PriceScope Tip: When it comes to fancy colored diamond (FCD) cutting you can throw away the normal cut-quality rules for D-Z colors. The goal with FCDs is cutting with angles which exaggerate the color present – which is opposite the goal for well-cut D-Z diamonds.
Pure red diamonds devoid of secondary hues are the rarest and highest priced in the world. At the 2011 Argyle Pink Diamond Tender, there was only one red diamond offered, a .80ct fancy red oval-cut. It takes one million carats of rough to yield a one-carat pink diamond to be sold at the tender, so imagine how much rough is extracted to produce a .80ct fancy red.

Red diamonds are distinct in the world of fancy-colored diamonds due to their rarity and beauty. Pure red diamonds without secondary hues are the rarest, making them the most expensive. Their unique formation and scarcity set them apart as true treasures in the world of fine jewelry and investment.
When it comes to fancy-colored diamonds, including red diamonds, the cutting process focuses on enhancing the color rather than adhering to traditional cutting rules used for white diamonds. The aim is to maximize the color’s intensity, making red diamonds even more captivating.

The natural formation of red diamonds is what makes them so rare. These diamonds owe their color to structural deformities, similar to pink and brown diamonds. These imperfections cause the diamond to refract light differently, resulting in the beautiful red hue. Pure red diamonds without secondary colors are extremely rare, and they command the highest prices in the market.
Cause of Color: Similar to pink and brown diamonds, color in red diamonds is generally thought to be caused by colored graining, which results from structural irregularities in combination with an impurity.
Secondary Colors: Red is the color between purple and orange, so common secondary colors in red diamonds include orangish red, purplish red and brownish red.
Rarity: Pure red diamonds are known to be the rarest of all fancy colored diamonds, and they command the highest prices. Weighing 5.11 carats the Moussaieff Red Diamond is the largest graded fancy red diamond in the world.
Grading: Red diamonds are graded as Fancy Red with modifying hues.
Mining: During its lifespan, Australia’s Argyle Diamond Mine produced most of the world’s red diamonds. The mine was closed in 2020. Brazil is another source of reds.
