The price of Violet Diamonds depends on the intensity of their colour.
A 0.16ct Si1 Round Diamond graded as Natural Fancy Grey Violet was available on 8th December 2017 for around AUD$52,000
Violet Diamonds are divided into eight categories:
- Very Light
- Fancy Light
- Fancy Intense
- Fancy Vivid and
- Fancy Deep/Fancy Dark
These are then further divided based on their secondary colours.
Always graded face up (flat side up) these diamonds will have the secondary colour listed first, followed by the main colour. The last colour mentioned is the most dominant colour.
Violet Diamonds are generally bluish greyish. Their colour is caused by either Boron or the combination of Hydrogen, Nitrogen & Nickel in their composition. Violet Diamonds usually occur with a secondary colour and are also a secondary colour to other diamonds.
The Argyle diamond mine in Australia, is the only known source of hydrogen and nitrogen rich diamonds coloured grey to blue to violet where up to about 0.20ct is common to be found. Faceted diamonds over 0.50ct are rare and (when available), the best diamonds of this colour variety are sold through the yearly Argyle Pink Diamond Tender.
In 32 years, only 12ct of polished violet diamonds have been offered at the yearly Argyle Pink Diamonds Tender.
In 2015 a 9.17ct rough violet diamond was discovered at the Argyle mine in Western Australia. It took over 80 hours to cut and polish this diamond into an oval shape of 2.83ct known as The Argyle Violet and graded by the GIA as a Natural Fancy Deep Greyish Bluish Violet. The Argyle Violet is included in the 2016 Argyle Pink Diamonds Tender which started in June travelling to Copenhagen, Hong Kong and New York. It is unknown at this stage how much this diamond will sell for, but it is estimated that the price can range from $2.5million to $5million.
