Why Choose a Certified Diamond?

When purchasing a modern diamond from a Brisbane supplier, certification is possibly the most important factor to consider when selecting a premium quality diamond.  Since the advancement of diamond cutting techniques in the early 2000’s  it is now possible to accurately produce a scientifically perfect cut diamond.

Internationally Recognised Laboratory Assessments

To assess the perfection of a diamonds cut, certification by laboratory grading equipment is required to provide such and accurate grading.  A store assessment or local valuation can provide a reasonable grading but is no longer sufficient for high quality diamonds. An international diamond certificate does not provide a value for the diamond but is a not-for-profit internationally recognised laboratory assessment of a diamonds quality so that it can be compared and valued with other stones and give a local valuation in the country that it is sold.

GIA, IGI and HRD Diamond Certificates

To assign a diamond its value a diamond needs to be accurately graded, which can only be identified if the diamond has an independently recognised diamond certificate. The best certificates for accurate understanding of the diamond that you are going to purchase are GIA, IGI and HRD.  These and just a select few others are the most trusted and accurate certifiers to confidently certify premium quality diamonds.

What is an International Diamond Certificate?

A diamond certificate is an independent (often non-profit) diamond grading assessment of an individual diamond that is provided by an internationally industry approved diamond grading laboratory.
Laboratory Inspection Diamond Grading Process

Laboratory Inspection Diamond Grading Process

The laboratory will inspect a diamond up to three times by different individuals using the highest standard diamond grading equipment to test the diamond’s carat weight, colour, clarity and most importantly the cut quality of the diamond. A diamond grading certificate is what gives a diamond its worth, without a certificate you are relying on only the opinion of the seller as to the assumed grade and quality of the diamond.

Certification for Diamonds Above 0.25ct

As most people purchasing a diamond do not have the skills or equipment to grade a diamond themselves, the international diamond certificate summarises the diamond’s quality in an easy to understand format. In the current market almost all diamonds above 0.25ct have been certified and the certification number is engraved into the girdle of the diamond for full security. If a diamond above 0.75ct does not have a genuine international diamond certificate then caution should be taken with its purchase as it can be considered that it is of a lower possible cut and the grading less accurate.

GIA, HRD, IGI, AGS, DCLA and ADGL Dimaond Cerificates

The most common and probably the only certificates that you should accept in Australia are GIA, HRD, IGI, AGS, DCLA, ADGL. It is important to understand that a diamond certificate is not a valuation, a diamond certificate only provides an assessment on the quality of the diamond and does not provide a price for the diamond.

Not all International Diamond Certification is The Same

Although most high quality diamonds will now be provided with an international diamond certificate it is also important to choose the right certification laboratory.

Choose the Right Diamond Certification Laboratory

There are several major international certification laboratories who operate in several counties and probably certify around 80% of all certified diamonds. However, not all international certification is graded to the same set of industry standards. Each of the certification laboratories grade by their own set of scientific standards, which requires the help of an industry expert when trying to select the right diamond.

GIA, IGI, HRD or AGS are the Leading Certification Laboratories Worldwide

For 100% satisfaction any high-end retail store should provide all of their diamonds with a reputable, leading independent diamond certifier such as GIA, IGI, HRD or AGS to ensure the client is getting exactly what they ordered. Diamond Brokers Queensland believe that for a diamond to be given the highest possible grading and the highest possible value, a GIA certified diamond has the highest reputation. If you wish to purchase a true ideal cut diamond that is perfectly cut in every way then GIA is the best selection.

Be Cautious of EGL Certified Diamonds

One other commonly found certificate is the EGL certification which has a completely different set of grading standards and although will be better than a non certified diamond the grading standard of this laboratory is well below that of the above certifiers. Generally an “Excellent” grade EGL diamond is equivalent to a “Good” grade GIA and so is the price. Unless you are looking for a lower value stone that sounds good on paper an EGL and any other non-recognised certifiers should be purchased with great caution.
