What is
Diamond Clarity?

The clarity grade is based on any tiny natural identifiers found within a diamond.

Most Ritani diamonds are free from inclusions that are visible without magnification. We recommend these diamonds for the best balance of quality and price.

The shape of a diamond can affect the importance of its clarity grade. While the brilliance facets patterns of round and princess-cut diamond can hide certain imperfections, step-cut shapes – such as emerald and asscher-cuts – have large, open tables. If you are searching for a step-cut diamond, we suggest looking at those with clarity grades of VS2 or higher.

SI2 clarity grade.


While natural diamonds have always been found to have inclusions and blemishes, a standardized method of assessing their clarity was not established until 1953. Gemologists at the GIA created a clarity grading scale that has since been revised twice.

In the 1970s, two new grades were added: Internally Flawless (IF) and Included 3 (I3). The latter of these grades was a response to a growing number of low clarity diamonds within the market. Originally, the 'I' of these lower grades represented 'imperfect'. 'Included' was considered to be more specific in nature.


The most popular diamond clarity grades with Ritani customers are VVS2 to VS2. These grades typically offer a great balance of value, as any imperfections – either on the surface or within the diamond’s structure – cannot be seen without magnification.

Many of our customers also opt for Slightly Included grades. These are good options for those wanting to prioritize another of the 4Cs – whether that is color, carat weight, or cut.

As the most popular shape, round brilliants are able to hide more inclusions than other diamond cuts. This is due to their brilliant facet pattern, which reflects light from lots of different angles as the diamond is viewed from the top. Other shapes with brilliance facet patterns include the princess, oval, marquise, and pear.

With step-cut shapes, such as the emerald and asscher, however, a higher clarity grade may be desirable. This is because these diamonds are shaped with larger tables – allowing you to see further down into the diamond. This potentially allows for inclusions and blemishes to be more visible, both under magnification and to the naked eye.

Choosing your clarity grade

When it comes to choosing a clarity grade for your engagement ring, it is best to keep in mind both the diamond shape and ring style that you want. A halo setting, for example, may limit the visibility of inclusions that are located closer to the diamond’s girdle. Prongs on a solitaire ring can also be positioned over more noticeable imperfections. If you are concerned about the inclusions in your diamond, talk to a Ritani Customer Service representative. They can guide your choice and ensure that your diamond is set in the best possible way.

As previously noted, some diamond shapes typically demand a higher clarity grade than others. If you adore brilliant facet patterns such as the popular round, princess or cushion cuts, you may not need to invest as much in a clarity grade than those looking at asscher or emerald-cuts.
