When you find the diamond jewellery of your dreams, you should be able to cherish it for a lifetime. Your selection needs to have a quality and craftsmanship that’s second to none, giving you pride and pleasure every time you wear it.

That’s why at Gerard McCabe, we have strict standards when selecting diamonds, gems and precious metals. With our selections, you can be confident that every diamond in a bridal ring or diamond jewellery has been assessed, and meets our strict criteria.

Cut

Diamond selection at Gerard McCabe starts with assessing the cut of the gemstone. When choosing a diamond, the cut has the most influence on its performance. That is, the intense sparkle that you want from your diamond. We look for diamonds that offer the very best performance, and each are individually selected for brilliance, fire and scintillation.

By having these impeccable diamond standards, our diamonds are typically within the top 15% of cut grading scales, with a triple excellent rating preferred. We work directly with the cutters ensuring our standards are met, so that we can give to you a diamond jewellery piece that is nothing short of exquisite.

Colour

The diamond colour grading is a measure of the colour, or the absence of colour, in the diamond. In this regard, the more colourless a diamond is, the more beautiful and valuable it is. Diamonds are measured on a scale from D (colourless) to Z (tinted yellow).

In order to create truly special Adelaide diamond jewellery, we hand select only premium quality diamonds for all of our bridal rings.

Also offering a range of gorgeous coloured diamonds in our Echunga Collection, with Gerard McCabe, you can rest assured that your selection is at the very height of value and craftsmanship.

Clarity

When it comes to diamonds, the clarity of the stone is incredibly important to the overall appearance and value of the ring. Diamond clarity grading is a measure of the prominence of inclusions within the gem and of external blemishes. Diamonds are natural gems, and so most will have some form of inclusion. This is what makes them unique, each as individual as the person who wears it. We like to think of inclusions as birthmarks in the diamonds.

Diamonds with minimal inclusions will be graded a higher clarity rating. To pass our clarity standards, our Adelaide diamonds must have minimal inclusions or the inclusions must be positioned so as not to impact on the visual beauty of the gem.

Carat Weight

A carat is a measurement of diamond weight. A metric carat is defined as 200 milligrams, and can be subdivided into 100 points. More often than not, the price of the diamond will increase with the carat size. 

Certificate

When purchasing a diamond, it is essential that you receive the proper certificates to ensure that your selection is authentic.

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

The diamond is also laser-inscribed with the Gerard McCabe logo and its unique diamond stock number, which is then linked to you, the purchaser. This is unlike any independent diamond certificate, offering peace of mind for you that we will always be able to track your diamond back to you.

We also stock diamonds that have been independently certified by GIA, the world’s most respected diamond grading laboratory. A GIA certificate offers an added security when selecting your diamond, so you can know that it has been assessed against the strictest criteria in the world.

Ethical Sourcing

Selecting the perfect Adelaide diamond ring is more than finding the most beautiful stone and design. In order for you to enjoy and love it to the fullest, you must have the assurance that your gorgeous diamond has been ethically sourced.

We believe in completely transparent and ethical trading in our industry.

We source our diamonds directly from the sight holder, following the guidelines of the Kimberley Process in the selection of our diamonds.

Under this system, all buyers and sellers of both rough and polished diamonds must make the following affirmative statement on all invoices:

“The diamonds herein invoiced have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions. The seller hereby guarantees that these diamonds are conflict-free, based on personal knowledge and /or written guarantees provided by the supplier of these diamonds.”

By working directly with a sight holder, we are able to track our diamonds back to their rough parcel, complying with the Kimberley Process warrant system and ensuring that the diamond has been obtained from a conflict-free source. We source our diamonds from the conflict-free mines in Canada, Russia and Africa. We also offer a selection of diamonds that come with Canada Mark Diamond Cards, offering absolute proof of Canadian origin.

We also have a variety of rare coloured diamonds which come mainly from Australia as well as other sources.

At Gerard McCabe, you can rest assured that your masterfully crafted diamond ring is second to none in value, design and authenticity. Explore our online collection of Adelaide diamond rings today to discover the piece of your dreams.
