For the less expensive colors, such as yellow and brown, clarity will be more of a factor. Red diamonds are known for their small sizes.
The majority of red diamonds on the market are less than 1 carat in weight. Only 5 red diamonds are known to exceed 5 carats in weight, the largest being 5.
Only a handful of red diamonds are discovered on an annual basis throughout the world, and most of them do not exceed 1 carat. Most red diamonds display fluorescence when placed under UV light.
In the case of colorless diamonds, the presence of fluorescence is generally considered to lower a diamond's value. This is in fact completely arbitrary, as the blue glow may or may not appeal to a buyer, but it certainly has no bearing on the composition, durability or beauty of a diamond.
However, it is a generally accepted notion in the diamond assessment world that the presence of fluorescence will lower a diamond's value.
Just like with clarity, in the case of fancy color diamonds, this is not a detracting characteristic if it is present. If anything, its presence ensures the buyer that the diamond is genuine, as fluorescence is not recreated in lab grown diamonds.
If a red diamond has fluorescence, it will not add or detract from its value or resale value in any way. Often, when a buyer is seriously interested in the purchase of a very expensive diamond, they will ask for the diamond to be examined by the Gemological Institute of America GIA to ascertain that it is genuine.
Of all the diamonds, red diamonds are the only ones whose size of under 1 carat will not disqualify them from being an investment stone, since so few red diamonds larger than that can be found in the market.
Red is not a commonly synthesized diamond color, as it does not usually appeal to the general mass of diamond consumers. The majority of red diamonds that are mined each year come from the Argyle diamond mine in Kimberley, Western Australia.
Since the majority of the world's pink diamonds are discovered in the Argyle Mine , it follows that the majority of red diamonds are discovered there as well, although this is not exclusively the case.
However, if a red diamond is traced to the Argyle mine in origin, it lends additional value to the diamond's price as is the case with all Argyle diamonds.

Sometime after the sale, DeYoung became suspicious about the identity of the stone. It was almost inclusion free, it had no signs of wear, and it had a complex cut.
All of these suggested that the stone was not a garnet. DeYoung took the stone for gemological testing, and the results were shocking.
The stone was a 5. DeYoung knew that the stone was valuable but passed away in , a year before the 0. His will directed that the diamond be given to the Smithsonian Institution upon his death.
Today The DeYoung Red is on display at the Smithsonian, in a case that is occupied by some of the world's largest, rarest, and most valuable diamonds.
It is the third-largest red diamond known to exist and the only red diamond on public display anywhere in the world. The country of origin of the diamond is unknown.
Since , the Argyle Mine in Western Australia has been the source of almost all of the few red diamonds that have entered the market. But, three of the world's most famous red diamonds came from other sources.
The Moussaieff Red, the largest red diamond known, was also found in Brazil sometime prior to its acquisition by William Goldberg Diamond Company in the mids.
The source of the DeYoung is unknown. The conclusion is that Argyle has not been the only source of red diamonds.
Perhaps more will be discovered in the future? Red diamonds have been produced by treating diamonds of other colors in a laboratory.
Irradiation followed by heat treatment or annealing has successfully altered the color of some diamonds to red.
Thin films applied to the surface of diamonds have successfully been used to produce diamonds of all colors, including red.

Synthetic diamonds have also been treated to a red color. GIA gemologists identified the stones as synthetic diamonds, and the red color was determined to be consistent with post-growth irradiation and heating.
An article about these treated synthetic diamonds was published in Gems and Gemology. It was one of the first published reports of synthetic diamonds that were identified to have post-growth color enhancement.
All of the diamonds in the collection had named colors, and the "intense red" color was named "Heavy Metal Cherry". Smit, Christopher M.
