Brown Diamonds natural or synthetic

Cognac, Champagne or Chocolate diamond

Causes of colour in heat treated brown diamonds and synthetic brown diamonds are similar to treated pink diamonds.

In natural diamond the colour is related to a lattice imperfection. This can be mimicked in synthetic or treated diamond by a variety of treatments including annealing, heating or irradiating. The heat and pressure or irradiation can result in the lattice deviation resulting in the brown or pink colour.

Synthetic brown diamond is created by compressing graphite under extreme pressure and heat to above 1500 Celsius. The treatments were perfected in several laboratories in Russia, United States and China.

Lazare Kaplan Internationals Belgium subsidiary Pegasus Overseas Ltd marketed the General Electric processed diamonds under the name GE POL or in the USA as Bellataire.

This led to a technique for creating, or treating brown diamonds into higher valued colours like yellow or colourless diamond.

The disclosure of the treatment is noted by the “GEPOL" inscribed on the girdles of every treated diamond.

Brown diamonds are often marketed with expensive sounding names like Cognac, Champagne or Chocolate diamonds. Natural brown diamonds are a cheap alternative to more expensive colours.

Lab Created diamonds Are like real thing says producer

DCLA DTC DiamondView

Consumers can now save thousands of dollars on diamonds, with a technological breakthrough that allows Synthetic diamonds to be created in a lab.

Bissell said the lab diamonds are not different in any material way and have all the optical, chemical and physical properties of mined diamonds, and they’re 100 percent carbon because they’re genuine diamonds.

The lab created diamonds are grown in pressurized containers on a small piece of carbon known as a seed,. The ultimate result is a high quality Synthetic diamond with the same properties as a natural diamond.

John King of the Gemmological Institute said lab grown diamonds are essentially the same as natural ones, and it’s just a matter of educating consumers.

To keep up with the new technology equipment to test stones and prove natural or synthetic is available at laboratories.

Created diamonds do come with certification from some laboratories with regard to colour and clarity.

In Australia DCLA does not certificate treated or synthetic diamonds and guarantees all diamonds ever submitted have been tested and are natural as stated on the certificate.

NOTE: If you have a certificate or report which does not say the diamond is natural, it has NOT been tested.

Open letter regarding over grading certification from the WFDB


Colleagues and friends,

The diamond industry is facing a serious challenge to its integrity which could lead to major consumer confidence problems, if diamonds are sold with overstated certification. I want to stress that this is an industry problem that must be resolved by the industry in order to retain consumer confidence in our product and sustain and develop the international diamond trade.

Recently, awareness was raised regarding problems existing within a specific laboratory group and the overstating of grading from certain laboratories in this group, which has led to the exclusion of said laboratories certificates by the Rapaport Group.

Your attention is drawn to the following issues:

(a) Ethical grading and certification are the most basic principles of the industry and these cannot be compromised.

(b) As part of the sales transaction the seller of diamonds provides a guarantee to the buyer of what is being sold and this forms a binding contract between the two parties. The seller cannot later hide behind an overstated grading report claiming ignorance as he/she will be held responsible regardless of any grading report supplied with the diamond(s) being sold. Diamantaires cannot hide behind certificates with the excuse that these goods sell cheaper. There is a common standard of colours and purities, and it is not about price but quality.

(c) In blatant cases the misrepresentation can amount to fraud with criminal consequences, depending on a countries consumer laws.

(d) Member Bourses must implement action in countries experiencing this kind of practice:

(i) If the offending party is a member, then the bourse concerned should take action under its own rules.

(ii) If the offending party is not a member, then the bourse concerned should report it to that countries consumer rights regulator in order to protect consumers rights..

On behalf of the Board and with regard to this issue, I commit the WFDB to ensure that we resolve matters as quickly as possible. We cannot reserve our position whilst this kind of practice prevails from a few laboratories that are damaging the entire diamond industry. Decisive and immediate action is required to eliminate this practice and the WFDB is in terms of its mandate compelled to take the lead. To this end a meeting will shortly be called of all the major laboratories to find common ground on the way forward.

I call on all responsible stakeholders across the world to stand together to eliminate this practice as it will harm our industry in a way that could dwarf any previous problems faced by the diamond industry.

I look forward to your full and ongoing support in this matter.
