What is the best diamond clarity?
The best diamond clarity is Flawless (FL). To explain, a Flawless diamond features no internal or external blemishes. Similarly, the Internally Flawless (IF) grade means the diamond has no internal flaws, but might have external blemishes. But how important is the Flawless or Internally Flawless grade for a diamond ring?
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.
Flawless diamonds demand very high prices. It is important to realise that you don’t need to choose an Internally Flawless diamond for the assurance of a high quality diamond.
Through our work at Serendipity Diamonds, we regularly advise clients to choose a good clarity grade. But not necessarily the best. In addition, we guide clients towards a good whiteness for the colour grade.
SI1 clarity diamonds work very well in the Daisy diamond cluster ring
Most of our diamond rings come in a choice of clarity. However, most rings with multiple diamonds are priced in SI1 clarity. Why? SI1 provides a clear diamond. Furthermore, most SI1 diamonds appear clear to the naked eye. Also know as eye-clean. Marks present in the stone remain unseen without use of a lens.
The above diamond bubble engagement ring is created using SI1 clarity diamonds —our standard for eye clean brilliance.
A few important notes on choosing diamond 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.
Why choose GIA certification when it comes to choosing clarity?
Most good quality diamonds above 0.30 carats include a report. Despite a certificate, some labs will grade diamonds better than they are. For this reason, we advise GIA reports. Their strict grading is well respected. GIA certified SI1 clarity diamonds appear clean to the naked eye. In contrast, some laboratories grade worse diamonds better. See below for an example.

SI1 Clarity and Emerald Cut Diamonds
Step cut diamonds (Emerald cut, Baguette cut, Carré cut) show marks more easily. For Emerald cuts, we advise buying VS1 clarity. This is important when choosing the best diamond clarity for your engagement ring.
Choosing the best clarity for big diamonds
Inclusions within 1.5 carat diamonds and above can be more visible due to the diamond size. A larger diamond will naturally has a larger table facet. Small marks below the table may be more visible to the naked eye. Once you see the inclusion, it can become easier to spot.
Choosing clarity when buying small diamonds
Small marks are less visible in small diamonds. For this reason, a diamond cluster ring will appear bright, and clear even when it has average clarity diamonds. Despite this, a less brilliance results from the inclusions in each diamond. For this reason, consider the size of diamonds when choosing the best diamond clarity for your ring.
