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 or diamond reports.

DCLA is currently the only internationally recognised laboratory not to issue Diamond Grading Reports for colour treated diamonds.

A preliminary colour authentication service is available upon request.

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.

Considering selling your diamond, but feel as though you have no idea how or where to begin ?

These simple tips will help you along the way.

TIP #1 Diamonds are usually given to display love, making the sentimental value higher to the seller than the actual value to a buyer. Should you be in the market to sell your diamond, make sure you are ready to part with the diamond before beginning the process.

TIP #2 Be sure of the quality and authenticity of what you are trying to sell. Make sure of the quality and the grade of the stone. This is most important for the ultimate value of the diamond. There have been many instances where a seller is committed to selling their diamond only to find out the quality isn’t as described when originally purchased.

There are Jewellers or services available, who will give an unbiased assessment of your stone. But it is far more valuable in the long run to get a report from a recognised Laboratory.

It is also recommended to verify the report matches the Laser inscription before placing your diamond on the market, to assure your diamond is the same stone should it not sell.

TIP #3 Now that you have an accurate report of the quality, make sure you get a realistic selling value. Believing the diamond holds a higher value than it truly possesses will lead to a challenging, frustrating experience which can be dragged out.
