Your diamond buying guide: What to consider before buying a diamond

25 Nov 21

After reading our diamond buying guide, you will have a deeper understanding of what you need to consider before buying a diamond to ensure you achieve the best return on investment. We will cover the following topics to help you going into the diamond buying process with confidence:

Know the 4 Cs of diamond quality

The value of a diamond is determined by the 4 Cs — carat, colour, clarity and cut. Before you decide to buy a diamond as an investment, it is absolutely essential to learn about these four elements to ensure you make your money go as far as it can.

We have a detailed guide to the 4 Cs available here, but we will provide a brief overview below:

Carat: The carat of a diamond is determined by the weight of the diamond. The bigger the diamond, the higher the carat weight. One carat is equal to 200 milligrams.

Colour: An international colour gradation system provides a code from D to Z, where D is fully colourless and Z is a yellow hue. A diamond with colour D is the most valuable. The colour of colourless investment diamonds varies between D and G. There are also coloured diamonds (brown, orange, pink, red, yellow, green or blue), some of which are very rare.

Clarity: Most diamonds have inclusions — impurities on the inside of the diamond. To measure the clarity, experts from an institute like GIA study the diamond for impurities under a tenfold magnification through a microscope and then score it.

Cut: Of all the diamond Cs, the cut is the most complex and technically difficult to analyse. The cut quality is determined by the proportions, symmetry and the extent to which the diamond shimmers.

For more details on the 4 Cs, you can also refer to this diamond buying guide chart by IGI, which provides helpful visuals on each aspect.

Always ask for a certified diamond

When buying a diamond, it is crucial that it comes with a certificate from a reputable independent lab, such as GIA, IGI or HRD.

A certificate, or diamond grading report, contains information about the diamond that supports its pricing, i.e., details on the 4 Cs.

Although you could buy a diamond without one, it would be unwise, particularly if you hope to sell the diamond in the future. Not only does a certificate act as a layer of security for you, but it will also reassure any future reputable buyers that it is a legitimate diamond, increasing the chances of a sale.

At BNT Diamonds, all our diamonds are certified by the GIA, HRD or IGI to give you peace of mind.

Choose a reputable seller

On the GIA website, it states that you should choose your diamond seller as you would choose a doctor. At BNT Diamonds, we agree.

When buying an investment diamond, you need to ensure that you’re buying from reputable experts who can help you make the right choice. This is true whether you are buying online or in-store.

Here’s what you need to consider before buying a diamond:

  • How long has the company been in business, and do they have stellar reviews?
  • Do the diamonds come with certificates from reputable laboratories?
  • Do they offer guidance and answer your questions in clear and simple language?

As with any investment, it is important to do your research to maximise your ROI and ensure that you are buying a natural, high-quality diamond.
