Special Valentine Diamond Laser Inscription

Cold Laser Inscription adds a timeless message to your diamond, as an expression of your love.

Laser inscription is the use of a very fine, precise laser beam to write a grading report number or customised personal message on the girdle (outside perimeter) of a diamond, which can be done even if the diamond is set in a ring or other piece of diamond jewellery. The laser inscription on the diamond is totally invisible to the naked eye and can only be seen with a magnifying loupe. It does not change the colour or clarity grade of a diamond and is considered permanent as it can only be removed by a professional diamond cutter. The DCLA uses the latest cold laser technology that allows excellent control during inscription without damaging the diamond (unlike a hot laser).

The inscription takes only five minutes, and the message lasts a lifetime. Both loose diamonds, and most diamonds set in diamond rings may be be laser inscribed.

Sample messages:

Jane & John 14/02/09

Certification of the diamond is not required for inscribing a personal message, any diamond may be inscribed. Several fonts are available, and a special Valentine offer is valid from now until the end of February.

DCLA issues Diamond Grading Guarantee Cards for Consumers

The Diamond Certification Laboratory of Australia (DCLA) announces the launch of a full-replacement guarantee to stand behind all DCLA Diamond Grading Certificates, providing complete and unsurpassed confidence for diamond consumers.

DCLA Offers New Damage Assessment and Recut Service

DCLA now offers a precise recut assessment service on poorly finished, chipped, broken, and otherwise damaged diamonds.

The popular belief is that diamonds are indestructable, but the fact is that diamonds can, and do in fact break, chip, or endure other such damage like abrasions and bruising. In most cases, the damage is repairable; DCLA has advanced equipment and specialised software to provide a comprehensive damage assessment report, and recut analysis, on damaged diamonds.

On request, DCLAwill have the diamond recut or polished. This service is available to the trade, members of the public, and insurers requiring salvage assessment.

New! DCLA Transparency Grading System

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.

RapNet to list DCLA graded diamonds

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.

DCLA welcomes new Director

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.
