About
DODAQ is the first online certified diamond exchange transforming the polished diamond industry from its existing weekly price sheet standard to a real time, automated pricing mechanism.
The introduction of polished certificates by recognised grading laboratories has allowed many diamonds to be traded based on certification without the necessity for physical inspection. This has also negated the traditional view that diamonds are non homogeneous and can now be rightfully seen as a tradable commodity.
Identifying this and concentrating on the main weight classes (between 0.30 and 1.49 carats) and shape (currently only round) DODAQ has devised a trading solution to service this high volume section of the industry. Using the grading categories and individual markets for each grading laboratory certificate, participants can enter both buy and sell orders for individual stones in a two-way auction thus creating a centralised electronic platform with real time spot prices.
The grading categories are as follows:
| Lab | Weight | Colour |
| Clarity | Make | Fluorescence |
All diamonds published on the DODAQ platform have first been graded by a recognised gemological grading laboratory and are received with their original certificates into the DODAQ vault. There are strict guidelines which determine the eligibility of those wishing to issue new diamonds onto DODAQ. For more information on issuer requirements see 'Guidelines for Issuing on DODAQ'.
