Diamond Clarity

Flawless has has no internal or magnification. They are exceptionally rare and represent the highest possible clarity grade and can only be found using our diamond selector tool.

Internally Flawless diamonds contain no internal inclusions, but may show very minor surface blemishes under 20x magnification. Like Flawless stones, they are extremely rare and highly valuable and cant be found via our diamond selector tool.

VVS1 diamonds contain extremely minute inclusions that can only be seen under 20x magnification, making them appear flawless to the naked eye.

VVS2 diamonds also contain minute inclusions, slightly more than VVS1, but still only visible under 20x magnification and never without specialist equipment.

VS1 diamonds have slightly larger inclusions than VVS grades, but these are only visible under 10x magnification and remain invisible without magnification.

VS2 diamonds contain a few more noticeable inclusions than VS1, but these are still only visible under 10x magnification and not with the naked eye.

SI1 diamonds have inclusions that are larger or more numerous, but we guarantee all SI1 diamonds are eye clean (with the exception of Emerald cuts). Many jewellers do not offer this reassurance, so if you are selecting through our diamond feed, please contact us to confirm your chosen stone meets this standard.

SI2 diamonds are the lowest clarity we offer at Purely Diamonds. Stones over 0.30ct may show inclusions visible to the naked eye, but they remain an excellent choice for earrings or pendants where the diamond is not examined as closely as in a ring.

If you select a diamond graded SI1 or above, it will be ‘eye-clean’, meaning the inclusions are too small to see without using magnification (This doesn’t apply to Emerald cut diamonds).

Please Note: This is not always the case with SI1 diamonds, Purely Diamonds specifically source SI1 stones that are eye-clean. Most other jewellers do not supply eye-clean SI1 diamonds.

Diamonds that are 0.30ct – 2.00ct (individually): If you select a diamond that is graded SI2 clarity, there will likely be some visible marks in the stone. They won’t necessarily be obvious to the naked eye but if you inspect the stone closely you might see some inclusions.

Diamonds smaller than 0.29ct (individually): Individual diamonds 0.29ct and under are all guaranteed to be eye clean. This means all single stone engagement rings, cluster style or wedding/eternity rings that contain diamonds smaller than 0.29ct (per diamond) will not contain any visible imperfections to the naked eye. To clarify; a half eternity ring that is displayed as 0.50ct total weight and has 10 diamonds will be eye clean as individually the diamonds are only 0.05ct each.
