Fancy Red Color Diamonds: A Guide to These Rare and Stunning Gems

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.

Red Diamonds Described

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.

The Cutting Process for Fancy Colored Diamonds

PriceScope Tip: When selecting a red diamond, prioritize color intensity over traditional cut standards. A well-cut fancy red diamond emphasizes its rich, deep hues, ensuring you get a stunning gemstone that stands out.

Pure red diamonds without secondary colors are extremely rare, and they command the highest prices in the market.
