Violet Diamonds

Pure violet diamonds without secondary modifying colors are impossibly rare, perhaps even rarer than purple diamonds. The presence of the trace element hydrogen in the atomic lattice is responsible for violet diamonds while purple diamonds are caused by plastic deformation. Violet diamonds and purple diamonds therefore consist of two separate colors.

Some industry professionals use the words “violet” and “purple” interchangeably. Violet diamonds are a distinct color group. Violet diamonds will appear more blue-grey to the eye while purple diamonds appear red or pinkish.

Fancy violet diamonds are assessed according to intensity of color, or a combination of saturation and tone. The more intense a diamond’s color saturation, the more it will be worth.

They are graded as follows: Fancy Violet, Fancy Intense Violet, Fancy Deep Violet and Fancy Dark Violet.
Violet diamonds of any kind are typically small and very rarely exceed one carat.
Natural fancy violet diamonds are extremely valuable. Even more valuable are those that are a pure violet color without any secondary modifying color. Modifying colors tend to devalue violet diamonds, but they are still exceptionally rare and will always be highly valued.

The Argyle Violet
The Argyle Violet, a 2.83 oval shaped violet diamond, is the dazzling centerpiece of the 2016 Argyle Pink Diamonds Tender. It is the largest violet diamond ever recovered from the Argyle mine.

Just 12 carats of polished violet diamonds have come from the Argyle mine over 32 years of mining.

The rough gem originally weighed 9.17 carats.
