The Moussaieff Red

The Moussaieff Red, or “Red Shield,” is a 5.11-carat red diamond and the largest of its kind in the world. This diamond was originally 13.9 carats in weight when a Brazilian farmer discovered it in the 1990s, and it was cut into a trilliant shape.

The DeYoung Red Diamond

The DeYoung Red Diamond is a 5.03 carat round cut red diamond, making it the world’s third largest red diamond. Named for the Boston jeweler who sold it and gave it to the Smithsonian’s Natural History Museum, the diamond is now on display there.

What Are The Most Popular Colors Of Diamonds?

One of the most prevalent mental images linked with the word “diamond” is that of a flawless, transparent gemstone. However, not all diamonds are colorless or transparent like a white diamond. Diamonds are available in a rainbow of hues and tones. Beautiful colored diamonds can be found in a wide range of tones, from yellow to blue and just about every shade in between. Popular diamond hues include:

Yellow Diamonds

The most popular fancy diamond color is yellow. Yellow diamonds, often called canary diamonds, have grown in popularity as an alternative to white diamonds in engagement rings and other forms of fine jewelry. Yellow diamonds can vary greatly in size and hue saturation. Yellow diamonds tend to be more valuable the more vivid and pure their color.

There is a wide price range for yellow diamonds, ranging from brownish-yellow (the most common) to greenish-yellow.

Blue Diamonds

The authenticity of blue diamonds is a perennially hot topic. Indeed, that is the case. Blue diamonds are frequently misidentified as sapphires due to their color. Sapphires and blue diamonds share certain visual similarities, yet they are fundamentally different stones. Boron particles become embedded in a diamond, transforming it into a blue gem. To produce a blue reflection, the boron must first absorb yellow light.

Diamonds of every color can be found in a wide range of cuts, carat weights, and tones, and blue diamonds are no exception. In addition to being one of the rarest diamond colors, blue diamonds are also among the most valuable. The Hope Diamond is undoubtedly the most well-known and renowned blue diamond in the world. This 45-carat blueish-green diamond is steeped in history, adding to its allure and worth.

Pink Diamonds

It’s no exaggeration to say that pink diamonds are among the rarest of all colored stones. You may think, “I’ve seen countless pink diamonds before!” However, the diamonds you’re seeing are likely synthetic rather than actual pink diamonds. Pink diamonds are exceptionally costly because of their scarcity.

Man-made pink diamonds are ideal if cost is a major consideration while shopping for a pink diamond. All sizes, colors, and intensities of pink diamonds exist. Less pure diamonds are less expensive than more pure ones. Rose gold, another member of the pink family, has been on the rise as a favorite setting for diamonds in recent years.


Taking your colored diamond to a reliable diamond buyer or appraiser is your best bet if you’re thinking about selling it. Don’t turn to pawn shops or internet auctions if you need money fast. Stores like these typically lack the expertise to determine a colored diamond’s fair market value. If you are the proud owner of a red diamond, the rarest and most valuable diamond color, you should stay away from those stores. Red or pink diamonds can fetch a high price on the market.
