Without a doubt, the modern-day consumers are more aware when purchasing precious metals like diamonds. But if you are purchasing the diamond for the very first time, there are certain things you need to know before buying any diamond jewellery online.


The very first thing that you must be aware of is the universally accepted 4C’s, which represent cut, carat, colour and clarity. However, these 4C’s are just to scratch the diamond’s surface, grading and market value.


Some reputed jewellers like Jewelslane offer you the online options to choose from the desired carat, colour, cut and clarity of the diamond. But do you know that in the modern era, another C (referring to Certificate) is also added to this evaluation criterion?


If you are confused by now, the following are the simple ways to know the accurate market value of the diamond you are investing in:

Carat

When buying diamond pendant online or any other diamond jewellery, you must know that carat is the most basic aspect of finding the diamond’s value. Carat actually refers to a diamond’s weight. For instance, 1 carat is equivalent to 0.2 grams.


Colour

Diamond colour grades depend on the scale from D-Z. D is totally void of any colour and considered very valuable. The Z has a yellowish tone, making it less desirable. Even some bright and fancy coloured diamonds have their own colour scale, varying from “faint” to “fancy deep.”


Cut

It is a commonly misunderstood factor as the shape of a diamond. But the cut is actually a measure of the quality depending on the thinnest and thickest points on the scale – varying from fair, good and very good to excellent. For instance, a ladies diamond bracelet with an “excellent cut” will have diamonds with perfectly thinnest and thickest parts, making it more expensive than the fair cut diamonds.


Clarity

Determining the clarity of a diamond is not easy with a naked eye. There are special tools to check blemishes or internal flaws in a diamond. A diamond that is graded “internally flawless” (IF), meaning without any blemishes, is very rare and highly valuable. On the other hand, if the diamond is graded “I1,” it means its inclusions can be seen with a naked eye.


Certificate

When buying a diamond from any jeweller, you need to check the certificates for trust and authenticity. The certificates usually include a serial number on its girdle, diamond quality, colour, organic validity, clarity, weight, etc.
