After analysing thousands of diamonds, DCLA has developed a new Transparency grading system, independent of other quality grades listed on the traditional diamond certificate.
Transparency is the degree to which a material transmits light, directly relevant to the cloudiness or haziness of the material.
Diamonds of any clarity, fluorescence and cut can in fact have Very Good or Excellent Transparency, making them attractive stones. Diamonds of any clarity, fluorescence and cut can also have Good or Medium Transparency – light return can be interrupted by multiple features of a given diamond.
The DCLA Transparency Grading System will now take all of these features into account to provide an even more comprehensive assessment of a diamond.
DCLA Transparency Scale:
Excellent – Completely transparent, no light interruption, no haze or cloud
Very Good – Transparent, minimal light interruption, very light haze or cloud, difficult to detect
Good – Transparent, slight visible haze or cloud, detectable
Medium – Semi-Transparent, marked light interruption, moderate haze or cloud, easy to detect
Poor – Semi-Transparent, very little light passes through, heavy haze or cloud
Effective September 15 2008, all DCLA Diamond Certificates will include the diamond transparency.
In addition, the DCLA has also split the traditional Finish grade on our Diamond Certificate into the dual features of Polish and Symmetry. This will provide a fuller, more detailed expression of the overall diamond make to both consumers and the trade.
The Diamond Certification Laboratory of Australia (DCLA) is proud to announce that RapNet, the World’s largest diamond trading network, will now include DCLA certified diamonds in its global listings.
From the 1st July 2008, Australian RapNet members can upload DCLA certificates onto the Network. This cooperation allows Australian merchants and retailers, for the first time, the ability to use RapNet to trade DCLA certified diamonds.
RapNet is an exclusive professional trading community giving members direct access to thousands of the best Diamond Suppliers and Buyers around the world. RapNet is a member only Network and is not open to the public.
After seven years at the helm, the outgoing directors are handing over control of the DCLA. The appointment of Ms Anna Wojcieszek as the new Laboratory Director marks the next phase in the laboratory’s growth.
Ms Wojcieszek has extensive diamond grading experience and spent several years in Gemmology and Client Development through the E.G.L USA Group in Canada. Holding a degree from the University of British Columbia, and studies at the Canadian Institute of Gemmology within the International Accredited Gemmologist (CIG) Diploma program which earned her the designated title of Diamond Expert (CIG), Ms Wojcieszek assumes responsibility for the DCLA.
The DCLA looks forward to continuing to provide unparalleled service as Australia’s foremost diamond grading laboratory.
Demand for branding in the Australian diamond market is the reason the DCLA ordered a second of the PhotoScribe cold laser systems. This will ensure fast turnaround time for certified and laser inscribed diamonds.
DCLA continues to be the only laboratory in Australia applying Cold Laser technology, the only laser guaranteed to not damage your diamond.
DCLA, the official CIBJO laboratory for Australia, received the C2 Au Registered National Diamond Master set for Australia. Cibjo, also known as the World Jewellery Confederation, is as a decision-making body whose main purpose is to create and maintain standards and promote cooperation among interconnected jewellery organisations. Among its other functions, Cibjo sets diamond grading policies for its member laboratories, including inspection and registration of diamond master sets.
The Diamond Certification Laboratory of Australia (DCLA,) was recently recognized as a CIBJO Registered Laboratory.
This is significant for Australia as it is the first diamond grading laboratory to achieve this recognition, DCLA reported in a statement. The DCLA was established in 2001 to address the standards of diamond grading in Australia.
Australia has a developed retail market and now has a laboratory which is recognized by both the IDC and CIBJO.
PhotoScribe cold laser system is now available in Australia. The DCLA has received the first of its kind in Australia, the latest cold laser technology that allows excellent control during inscription without damaging the diamond.
The service will be offered with all DCLA certificates and as a branding option. This system can perform complex images and two dimensional bar-coding.
The Diamond Certification Laboratory of Australia (DCLA), Sydney, Australia is proud to announce that it has become only the fifth diamond certification laboratory worldwide to be accepted as grading to IDC Rules.
After a strict and lengthy auditing procedure, DCLA was granted the Rules by Mr. Les Milner of the SAJC.
The IDC Rules are the diamond grading guidelines devised by the International Diamond Council (IDC), which was set up in 1978 by the World Federation of Diamond Bourses (WFDB) and the International Diamond Manufacturers Association (IDMA). There are currently five gemmological laboratories worldwide that apply the IDC Rule Book. They are:
- The Certificates Department of the Antwerp Diamond High Council (HRD), Belgium
- The Swedish Testing Institute (SSEF), Sweden
- The Jewellery Council of South Africa Laboratory (SAJC), South Africa
- The Diamant Prueflabor, Idar Oberstein, Germany
- The Diamond Certification Laboratory of Australia (DCLA), Australia
