Famous Natural Purple Diamonds

Purple diamonds are often held to very high standards as the color represent wealth, royalty, power, and ambition. The most famous purple diamonds over the years are not only exquisitely beautiful but also larger than average in size. The average size of a purple diamond is below 5 carats, which is another characteristic setting these gems apart from colorless diamonds.

The “Royal Purple Heart” is a diamond of which very little is known. What is know, the diamond's heart shape and size, has captivated the eyes of many. It was mined in Russia and is said to be the largest fancy vivid purple to date, weighing 7.34 carats.

Another famous natural purple diamond is the “Supreme Purple Diamond Heart,” all that is known about this diamond is that it weights between 2-5 carats and it is flawlessly round in shape. Despite its comparatively smaller size, its captivating color is what makes it so popular. It is said that its color can show different shades of purple depending on the angle from which it s viewed.


Naturally colored diamonds, just like colorless diamonds are formed through a highly pressured process involving carbon molecules.  It is when other elements find their way into the mix that a naturally colored hue appears. Although scientists are not certain of the how purple and violet diamonds obtain their color, it is thought that the hydrogen plays a part in their formation. These rare purple colored diamonds account for about 0.2% of the global diamond inventory.

Many natural purple diamonds are naturally modified by secondary hues of pink, red, blue, or gray.. Pure fancy purple diamonds are divided into two categories: purple diamonds, which have secondary hues of pink and red, and violet diamonds, which have secondary hues of blue and gray. Of course, the higher the presence of these modifiers, the more the overall perceived value of the gem declines. The tone of the color purple occurs in five intensities from very light to deep and vivid. The value of the diamonds depends highly on where the color is classified on the spectrum.


Purple diamonds are nearly impossible to find, making it the second rarest color after red diamonds. So where can purple diamonds be found?

These precious stones have been sourced from mines in Russia, Brazil, Canada and most commonly the Argyle Mine in Australia. The Siberian mines in Russia mostly produce pale purple diamonds and only account for 1% of their output. Darker and more vivid colors can be found in Australian mines.

Naturally fancy purple diamonds are such rare beauties; regardless of their size, they are exceedingly valuable and highly sought-after gems by collectors and investors.
