1. What is a red diamond?
Red diamonds are the most expensive and rarest color diamonds in the world. Even red diamonds are rarer than pink or blue diamonds. In the history of the gem industry, fewer than 30 natural red diamonds have ever been found.
Unlike other colored diamonds, the red pigment of red diamonds is not created from impurities such as nitrogen present in the composition of red diamonds. In fact, the exact cause of the red color of diamonds is still unknown.
Some geologists believe that the red color of diamonds comes from changes in the atomic structure – a phenomenon called plastic deformation – that occur during the diamond’s push to the Earth’s surface. Similar to pink diamonds, extreme pressure affects their molecular structure. With this theory, higher pressure means darker red.
2. Origin of the red diamond?
Since 1985, the Argyle diamond mine in Western Australia has been the source of nearly all of the few red diamonds entering the market. However, the three most famous diamonds in the world come from other sources and from the time when the Argyle diamond mine was untapped. Therefore, Argyle is not the only source of this color diamond.
Not knowing the exact origin as well as the place of origin adds to the mystery of the stone, as it is an extremely rare type of 12 unique colored diamonds.
3. Other types of red diamonds
3.1. Synthetic red diamond (Lab-grown diamond)
Synthetic diamonds are cheaper, environmentally friendly, and do not have conflicts like destroying the ecosystem. Man-made diamonds control to mimic the processes and properties of natural diamonds. Currently, the research laboratories have made many kinds of artificial colored diamonds.
3.2. Red fire diamonds
For the purpose of changing the color or intensity of a diamond’s color, through irradiation, man-made diamonds (which can be white, yellow, or blue) or natural white diamonds are bombarded with neutrons or electrons to change the structure of the crystal lattice, which changes their color. The mixture is then heated to achieve the desired red intensity.
These two grades are much more economical than natural diamonds, but keep in mind that they still cost more than other artificial or irradiated colored diamonds.
4. The price of natural red diamonds and the stones that shook the world

Today, the DeYoung Red is the only red diamond on display. at the Smithsonian, in a box containing some of the largest, rarest, most expensive diamonds in the world.
5. How are red diamonds rated in the 4C diamond standard?
Extremely rare large-size red diamonds. In fact, the largest known stone – Moussaieff Red – weighs only 5.11 carats. All other natural pellets are less than 1ct in size. However, man-made diamonds offer a wider selection and you may find a stone that is slightly larger.
Color and Clarity
With red diamonds, color is the most important criterion. You should pay attention to how it looks in different lighting conditions when buying. For example, they look best in natural light and worst in fluorescent light.
The cut of a diamond can significantly affect the sparkling appearance. For red diamonds, the oval will be the most flattering design. In contrast, circles tend to reduce their luminescence.
Like all diamonds, red diamonds score 10 (hardest) on the Mohs hardness scale.
6. Red diamond meanings
