This question crops up regularly. It is worthwhile finding out the most suitable clarity for an engagement ring—without spending too much on perfecting clarity. Beyond a certain point, you will see no visible difference to the naked eye.
A Diamond clarity grade gives a standardised value expressing the concentration of natural characteristics present within a diamond.
What is the best diamond clarity for an engagement ring.
The first answer is that there is no standard clarity. Manufacturers choose a diamond clarity based on cost, availability and what they feel buyers will settle for. Many high street retailers stock lower clarity rings based on price alone. Many are set with light-weight ring mounts again purchased on cost.
Most of our diamond solitaire rings can be made in a very wide selection of clarity grades, but our multi stone engagement rings (e.g. 3 stone rings) appear with one clarity. SI1. We feel that this clarity grade is best for engagement rings. Defined as ‘eye clean’ diamonds meeting an SI1 clarity grade will appear clear to the eye. Slight inclusions present remain unseen without the assistance of a lens.
The above diamond bubble engagement ring is created using SI1 clarity diamonds —our standard for eye clean brilliance.
Important : consider the following notes on clarity
There are some important notes to consider when choosing the best diamond clarity for an engagement ring. Although the SI1 clarity level is suitable for many rings, please keep in mind the following.
Choose GIA certification
Single stone rings above 0.25cts will potentially include a diamond certificate. Some laboratories are far too generous with their grading. We advise GIA certification to ensure that the diamond has been graded strictly. GIA certified SI1 clarity diamonds will be completely clean to the naked eye. This is especially true for diamonds between 0.30cts to 1 carat in weight.

Exception to the SI1 rule – Emerald cut diamonds
Step cut diamonds (Emerald cut, Baguette cut, Carré cut) are less forgiving when it comes to clarity compared to brilliant cuts. If you are considering an Emerald cut diamond, we recommend VS1 clarity. This is an important consideration when you are choosing the best diamond clarity for your engagement ring.
Larger certified diamonds
Inclusions within 1.5 carat diamonds and above can be more visible due to the diamond size. A larger diamond will naturally possess a larger table facet. Slight inclusions below the table may be slightly visible to the naked eye. This is especially true once you know the location of the inclusion.
