Diamond clarity refers to the presence of inclusions and blemishes on the surface or inside a diamond. It is graded at 10X magnification on a scale that ranges from FL (Flawless) to I1-I3 (Included).
All Rolary lab-grown diamonds are VVS1 (Very Slightly Included) to SI1 (Slightly Included) VS1-VS2 (Very Slightly Included): Minor inclusions are observed with an effort at 10x magnification. SI1 (Slightly Included): Inclusions are noticeable at 10x magnification. This is the best value for eye-clean clarity. This also means that when set in jewelry, non-professionals typically see clean, beautiful, and radiant diamonds to the naked eye, and you would barely notice any inclusions. The price changes according to the specifications you choose. We recommend the grades from our list as they are the best value for the price. For any grade beyond the range listed, you can reach out to customer support directly for the quote. The selected grade is a minimum guaranteed. The clarity grade of your actual diamond may be equal to or higher than the selected grade purchased.
