At Gerard McCabe, we have a passion for exceptional diamonds. Working directly with the sight holder, we seek the highest quality diamonds, looking for exquisite and high-performing gems which are individually selected for brilliance, fire and scintillation.

And, as we follow strict standards when selecting diamonds, gems and precious metals, you can be confident that every one of our stunning diamond jewellery pieces has been assessed to meet our high standards.

We offer a range of certification options to consider in the selection of your diamond:

Gerard McCabe Certificate

All Gerard McCabe diamonds that are 0.30ct and larger come with a Gerard McCabe certificate and card.

A Gerard McCabe diamond certificate ensures the following lifetime guarantee -

The 4Cs of the diamond

This refers to our diamonds' cut, colour, clarity and carat. All our diamonds are assessed against our strict standards.

Security and traceability

Each diamond’s girdle is laser inscribed with its unique identifying Gerard McCabe certificate number along with our logo. This number is given to you with your certificate and recorded in our database, so the diamond is able to be uniquely tracked back to the purchaser.

Ethically sourced supply

At Gerard McCabe, we believe that a diamond’s beauty should never be marred by its history. As such, we only use ethically sourced diamonds in our Adelaide jewellery. By purchasing our diamonds directly from the sight holder and following the guidelines of the Kimberley Process in the selection of our diamonds, we ensure that our diamonds are from the conflict-free mines of Canada, Russia and Africa.

Additionally, all of our diamonds come with their known rough (birth) weights on their Gerard McCabe diamond certificate card.

GIA Certificate

In addition to the Gerard McCabe certificate and when independent certification is an important factor for your diamond purchase, we offer a selection of diamonds certified by the most respected diamond grading laboratory in the world, the Gemological Institute of America (GIA).

Diamonds that are certified by the GIA can be verified on their website, and the GIA certification number can be found laser inscribed on the girdle of the diamond.

Canada Mark Card

For customers whom the provenance of their diamond is paramount, we offer you a selection of diamonds which are mined in Canada and come with a Canada Mark Diamond Card. This card offers absolute proof of Canadian origin; it also states the rough (birth) weight and the finished weight of the gem. These diamonds have a unique identifying number which can be verified on the Canada Mark website and this number is laser inscribed on the girdle of the diamond.

At Gerard McCabe, we understand that the diamond you select needs to be a perfect fit for your needs. But, more than that, it needs to carry with it authenticity and the undisputable knowledge that its past was as bright and flawless as the stone itself.
