Things To Know Before You Buy A Diamond

Buying diamonds can be an extremely overwhelming process. One questions whether the diamonds are worth the value they’re paying for. You will find the important things to know before you buy a diamond in this article. There are a few factors to keep in mind to determine the quality and the value of the stone. While most diamonds might look quite similar, there are small factors and attributes which differentiates them from one another. However, diamond prices depends on these factors. There are four very important things to consider when choosing a diamond, the 4C’s: Cut, Colour, Clarity and Carat. 

1. Cut

Diamond Cut Quality

The cut refers to a diamond’s proportions, facets and shape. The beauty of a diamond depends more on cut than any other factor as it affects its appearance in terms of brilliance and the sparkle. A properly cut and polished diamond will reflect and disperse light to provide maximum shine. Cuts are typically graded on a scale of 5 from excelling to poor depending upon the amount of light reflected. Depending upon your budget, diamonds with lower colour and clarity can still provide high sparkle if they’re cut in the right proportion and shape. 

PRO TIP: It is suggested to always stick to the excellent to very good range as they work the best with light. For fancy shapes such as marquise, oval, emerald and pear, a good thumb rule would be to maintain a well balanced length to width ratio scale. 

2. Clarity

Clarity of a diamond

The clarity of a diamond is determined by the number of inclusions and flaws in the stone. Inclusions are very small imperfections that naturally occur in the formation of diamonds and gemstones which interfere with the amount of light that passes through the stone. Clarity ratings range from Flawless (FL) to Included (I). A higher clarity stone commands a higher price point. Additionally, the diamond shape also determines the number of visible inclusions. Emerald cut diamond makes imperfections more visible to the naked eye in comparison to round brilliant cut diamonds. 

PRO TIP: To get the maximum value out of your diamond, the key is to find a good balance between the colour and clarity. For instance, a higher colour (G-H) and a lower clarity (VS1-VS2)  can save you a lot of money as long as there are no visible inclusions. 

3. Colour

Colour quality of a diamond

Natural diamonds are found in a huge range of colours and are rated on a scale from D to Z- D being completely colourless and Z being light yellow in colour. A colourless diamond carries a higher value in comparison to a stone with a colour presence. While the difference may not be visible with the naked eye, they do have a major impact on the price of the stone. 

PRO TIP:  With round and emerald cuts, you can typically go as low as J colour without seeing a noticeable colour. On the other hand with other fancy shapes, you need to go a bit higher on the scale (H and up) to not see any colour. 

4. Carat

Carat of a diamond

It refers to the actual weight of the diamond. The GIA defines carat as 0.02 grams. Larger carat diamonds tend to be rarer and more desirable. Also, two diamonds of the same carat may vary greatly in price depending upon other factors such as cut, colour and clarity. 

PRO TIP: Another interesting fact is that two diamonds of the same carat can appear to be different sizes. For instance, you could potentially find a diamond that weighs 1.00 carat but appears closer to a 1.20 carat stone. So technically you’re buying a stone that looks larger without any extra cost in terms of per carat rate.
