Clarity

Diamond clarity is a term used to describe the absence or presence of inclusions inside or on the surface of a diamond. Diamond clarity is one of the most important factors for selecting and pricing a diamond, in addition to diamond carat and diamond colour.

What Does Diamond Clarity Refer To?

Diamond clarity refers to inclusions in the diamond. These inclusions might be black, grey or white marks that are present inside the diamond's structure. These imperfections are natural and graded under x10 magnification, which is the standard for grading diamond clarity.

Diamond Clarity Factors

Grades are assigned after taking into account various diamond clarity factors. Diamond clarity factors include the:

  • Amount of inclusions
  • Size of inclusions
  • Nature of the inclusions
  • Position of the inclusions
  • Colour of the inclusions

Each factor is thoroughly examined so that the diamond is graded appropriately.

Group Grading :For multi-stone items of diamond jewellery such as diamond bracelets, diamond eternity rings, Multi-stone pendants etc. we provide a Diamond Factory & EGL Jewellery Certificate of Authenticity which confirms the combined diamond carat weight and diamond quality for your peace of mind in the quality of your diamond jewellery purchase. Obviously multi-stone jewellery have more than one diamond and so, we offer a range of grading options like clarity grades I1, SI, VS and VVS. It is very difficult to source the specific the grades of diamond, when many diamonds need to match together exactly.

Top Tips

To help you choose the diamond clarity that is perfect for you, we have collated a few top tips:


If you cannot tolerate imperfections that are visible to the naked eye, you should consider our most popular grade, which is VS1-VS2. These diamonds appear flawless to the naked eye and are a fraction of the price of a flawless diamond (FL-IF). Visibility of inclusions to the naked eye also depends on size, cut and certifying laboratories. For example, SI1 grade of EGL have high chances of visible inclusion compared with GIA grade examples. In the same respect inclusions are more visible in larger size diamonds, for example, a 1.50ct diamond in SI1 has more visible inclusions than a 0.50ct diamond.
The most popular range is SI1, where the inclusions are usually not significant enough to impact on the appearance of the diamond for the casual observer. This clarity grade often results in a beautiful, lively diamond, with imperfections detectable upon close inspection.
If you are primarily concerned with size and price, I1 or SI2 may be your best clarity option. While the inclusions are visible to the unaided eye, many very happy customers find it well worth the sacrifice to get the desired size.
Brilliant-cut diamonds (such as Round, Princess, Cushion, Oval, Pear, and Marquise) hide inclusions better than step cuts (Emerald, Asscher). When purchasing a step-cut, move up one clarity grade (e.g. purchase a VS2 or above instead of SI1 if you desire the lowest grade that has no visible inclusions).

Each factor is thoroughly examined so that the diamond is graded appropriately.

 

Diamond Clarity Grading Chart

Please view the clarity grading chart below, to determine the most common grading categories and the corresponding factors

Internally flawless. Diamonds in this grade have no visible flaws even when examined at x10 magnification.

Very, very slight inclusion. Diamonds with a VVS1 or VVS2 grade have barely any inclusions and these can only be found under very high magnification.

Very slight inclusion. VS2 diamonds have a series of tiny inclusions that in common with the VS1 grade can only be discovered using x10 magnification. VS2 clarity diamonds are extremely popular as they are the grade which virtually guarantees inclusions are eye clean (not visible to the naked eye) diamonds. In most cases VS2 diamonds are eye clean. Rare exceptions may include VS2 diamonds on DF and in certain cases, Emerald and Asscher cut diamonds, which may not always be eye clean, even on IGI/GIA certificates. The type of inclusions here would generally consist of two small inclusions or a series of tiny ones. Diamonds of VS clarity are of outstanding quality.

SI1: Slight inclusion. Slight inclusions are easily found under x10 magnification. SI1 graded diamonds have small inclusions that will almost always be visible to the naked eye. SI1 clarity diamonds can offer exceptional value for those wishing to maximize their budget.

SI2: Slight inclusion. Diamonds have a greater number of inclusions that will almost always be visible to the naked eye.

Inclusion. Diamonds have numerous inclusions that can easily be seen. Diamonds of this clarity represent incredible value compared with higher clarity grades. These diamonds are perfect for people not sensitive to the presence of inclusions, but want a larger size (or weight) of diamond.

Inclusions Are Naturally Occurring

Remember, inclusions are naturally occurring. Each diamond is unique, partly because of inclusions. You can view an inclusion as a flaw, or as naturally occurring and unique characteristic of your diamond.
