The 4Cs – cut, colour, clarity and carat – are crucial for you to consider when buying a diamond. As each of those determine the value of the gem. A change in one or all, can lead to an increase or decrease in value and price.


Or the shape of the diamond. Round-brilliant is the most popular and highly desirable for the brilliance (more on this later). Every other cut that is not round is a fancy shape.


Or rather, lack of colour, for white diamonds. Measured on a scale from D to Z. With D, E and F the top 3.


How (if any) many inclusions or blemishes, visible under x10 magnification. We use a loupe to determine the amount of inclusions. Taking into account size, nature, position, colour and number of inclusions. How many there are, how they came about (nature) are determinants of value. All else being equal, the higher the clarity the higher the value. Clarity ranges from flawless (IF) at the top end, very slightly included (VS1) in the middle, to I (included) at the lower end.


Or the weight. 1 carat = 0.20 grams.

A Millennial’s Guide to Buying Diamonds

We can all relate to those viral memes about #adulting – what on earth are we doing? Should I be buying this? Who knows! Our parents’ dream of white picket fence and 2.5 children, has been replaced with #millenialmagic, the ultimate in life goals. Juggling being an art dealer-cum-photographer-cum-CEO-cum-graphic designer-cum-accountant. Meaning it is difficult to know what it is we want and where to begin.

When speaking to my Gen Z relatives about this millennial’s guide to buying diamonds, they chuckled and said: Don’t complicate any of it. Think of it this way… One day we are trying to figure out the best filter to use on Snapchat, the next day we are trying to combat climate change and which career path to take. If I were you, I’d keep it simple, that is the easiest way to explain and understand gemstones. Stellar advice! So here goes…

How to Buy a Diamond?

Whether you’re popping the question (proposing) or buying yourself a ‘well done for being awesome’ gift, you have to take into account the same factors, when deciding how to buy a diamond.

The Basics

The 4Cs of a diamond: as above.
Mohs: 10
The cut (shape) determines the brilliance, scintillation and how ‘sparkly‘ the diamond looks. #Tbt to physics lessons in secondary school. The amount of light that enters (the pavilion) and leaves (through dispersion) in each stone, determines how ‘shiny‘ or ‘sparkly’ it is. If the pavilion is too shallow, it’ll appear less sparkly. In the words of sagacious Rihanna, “shine bright […} like diamonds in the sky.”
A diamond is durable and can be set into all your heart’s desire. From earrings, to bracelets, a pendant or a ring.

Tips and Advice

1. Insist on a diamond grading report.
The differences in diamond quality can be so subtle even a trained jeweller can’t recognize them without lab verification. Insist that any diamond you buy comes with an indisputable verification of its quality from an unbiased source.

2. Protect your purchase.
Have your diamond appraised and insured. Appraisers and insurers rely on diamond grading reports to accurately evaluate the value of gems. As an additional measure, consider having your diamond laser-inscribed with its GIA report number, to provide verification if it is ever lost or stolen.

3. Look for a gem that weighs a bit less than your target size.
Prices per carat generally increase as the weight passes “magic numbers” such as 1.00, 1.50, and 2.00 carats. A diamond that weighs 0.95 carat will cost less per carat than a 1.00 carat stone but look almost the same.
