Colour Authentication
Fancy Coloured Diamonds
The origin of colour in fancy coloured diamonds is of paramount importance to its value. A diamond will either be of natural colour origin as created by nature, or else it has been treated and enhanced by man.
DCLA authenticates all fancy coloured diamonds as natural prior to certification.
DCLA will not issue Diamond Grading Reports for colour treated diamonds.
A preliminary colour authentication service is available upon request.
Colourless Diamonds
Certain “white” diamonds may be enhanced to improve their colour as well. All diamonds that come into the DCLA laboratory are screened for enhancements, and referred for further testing if they do not pass the initial screening. DCLA will only issue a Diamond Grading Certificate for diamonds of natural colour origin.
Synthetic Diamond Identification
All diamonds that come into the DCLA laboratory are screened to ensure that they are natural and not man-made. Diamonds that do not pass the initial screening are referred for further testing.
DCLA will not issue Diamond Grading Reports for synthetic diamonds.
A preliminary synthetic diamond identification service is available upon request.
The diamond trading floor that gives all diamond buyers direct access to DCLA guaranteed diamonds from Australian diamond dealers.
