Is Diamond Clarity Important?

When choosing a diamond, people are typically guided firstly by budget, next by the size (carat weight) of the diamond, and then by the quality. The clarity is one of the attributes that contributes to the quality of a diamond. Its true to say that you don't need to have the highest clarity to achieve a beautiful looking diamond. The diamond clarity is important but less important when buying a diamond from 1791 Diamonds Ltd, because our strict diamond quality policy means we only sell high quality beautiful diamonds.

We hope you find this guide to buying designer Engagement Rings helpful but if you have any questions please don't hesitate to contact customer services.

Diamond Clarity Explained

A diamond is a natural substance that comes from the ground, therefore unless a diamond is classified as internally flawless there will be tiny inclusions inside each diamond. These inclusions may be other minerals, liquids or even gases trapped inside the diamond as it was formed. Most of these inclusions are so tiny that they are not visible with the naked eye.

The Diamond Clarity scale was introduced to identify the quality of a diamond based on the number, type and position of its inclusion. To determine the clarity diamonds are graded under 10 x magnification. The Diamond Clarity grading scale runs from absolutely flawless (FL) right through to flaws (I1-I3) that can even be seen with the untrained naked eye. Don't worry, 1791 Diamonds Ltd doesn't sell the latter!

What Diamond Clarity should I choose?

Unless you have a very large budget it is not necessary to buy an internally flawless diamond. Even with a large 1.00 carat diamond it is impossible to see the difference between a VS1 clarity and an IF clarity diamond with the naked eye alone. You would need to study the diamond under magnification to see any inclusions.

However, you should increase you discernment by picking a higher clarity grade when buying larger diamonds or ones with large wide open top faces such as Emeralds and Princesses because its easier to see inclusions in these diamonds.

Stay at or above SI2 at all times. 1791 diamonds Ltd does not sell any diamonds lower than an SI2 in clarity. Stay at or above SI1 if the diamond is over 0.5 carat in size, and ideally at or above VS2 if the diamond is over 0.75 carats.

Our staff have all attended diamond grading courses so will be able to help you choose the best diamond for your budget and often save you money too. Don't worry, even if you do make your own decision, we will of course make a recommendation when the order comes through if we think there is a better option available.

Diamond Clarity Terms in Detail

The below terms a quite complex, a simple guide is to look at SI grades or better with FL as the highest diamond clarity grade.

- FL - IF (Flawless or Internally Flawless). This is the top diamond clarity grade, some diamonds in this grade have inclusions that can't even be seen with a jeweller's 10x magnification loupe. If there are no imperfections seen under 10x magnification; diamond graders may use stronger magnification tools to find the inclusions or imperfections, if inclusions are found then the diamond would be given a lower grade like a VVS1 for example.

- VVS (Very, Very Slightly Included). Diamonds with a VVS clarity have small inclusions which even experienced diamond graders have trouble locating with a loupe. Small pinpoints, hairline feathers and even a cluster of tiny pinpoints creating a subtle cloud are attributes that would give a diamond a VVS clarity grade. VVS1 and VVS2 clarity grades are used to separate between high and low ends of this grade when the diamonds are over 47 points (0.47ct).

- VS (Very Slightly Included). The diamond clarity grade VS refers to diamonds with inclusions that are small in appearance. With the VS clarity grade, experienced diamond graders can still have trouble finding the inclusions, however once found the inclusions are easily found the second time. Sub grades VS1 and VS2 are used to separate between the high and low ends of the VS clarity grade, these sub grades are used when diamonds exceed 47 points (0.47ct).

- SI (Slightly Included). The SI1 clarity grade includes diamonds that have inclusions that can be easily found with a 10x magnification loupe, while some of the inclusions in the SI1 grade can be seen with the naked eye. Sub grades SI1 and SI2 are used to separate between the high and low levels of the SI clarity grade, these sub grades are also used when the stone exceeds 0.47 diamond carats.

- P or I (Pique or Imperfect). The I clarity grade includes diamonds that have inclusions which are instantly visible with a 10x loupe, and they can often be seen with the naked eye alone. I clarity grade diamonds reduce fire, brilliance and sometimes the durability of the diamond, the inclusions will noticably affect the beauty of the stone. Attributes of an I grade diamond include dark crystals, big fractures and dark marks in the diamond.

Diamond Clarity Certification

At 1791 Diamonds New Zealand we provide a full Independent Diamond Grading Certificate with every diamond engagement ring. This is very important with engagement rings as this is the only way that the customer has proof of the true quality of the diamond, many retailers may provide a diamond certificate but if this is not independent then you cannot be sure of the legitimacy of the document.
