Carats measure the weight of the diamond but also affect the size. One carat is equal to 0.2 grams.

The total weight of our products may vary, so please see the table below for more information about the carat weights we offer:

Cut quality refers to how well the diamond is cut in terms of the angles and proportions. This is an important aspect of diamond beauty as it affects how the light shines through the diamond.

All Rolary loose lab-grown diamonds are consistently made to a high standard. Our state-of-the-art technology means our lab-grown diamonds are among the highest qualities on the market. Rolary diamonds meet the internationally recognized standards for cut quality as described below:

The color scale is a grading of a diamond’s quality based on the absence of color. Diamond color is graded on a scale from D (Colorless) to Z (Noticeable Color) by GIA. DEF are considered Colorless, while GHIJ are considered Near Colorless.

The color of all Rolary lab diamonds falls between D (Colorless) to I (Near Colorless).

The price changes according to the specifications you choose. For any grade beyond the range listed, you can reach out to customer support directly for the quote.

Your chosen grade is a minimum guaranteed. The color grade of your actual diamond may be equal to or higher than the selected grade purchased.

Diamond clarity refers to the presence of inclusions and blemishes on the surface or inside a diamond. It is graded at 10× magnification on a scale that ranges from FL (Flawless) to I1-I3 (Included).

All Rolary lab-grown diamonds are VVS1 (Very, Very Slightly Included) to SI1 (Slightly Included)

• VVS1-VVS2 (Very, Very Slightly Included): Minute inclusions that range from extremely difficult (VVS1) to very difficult (VVS2) to see at 10× magnification by a trained gemologist.
• VS1-VS2 (Very Slightly Included): Minor inclusions are observed with an effort at 10× magnification.
• SI1 (Slightly Included): Inclusions are noticeable at 10× 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.

Every loose diamond at Rolary™ is certified by one of the globally recognized organizations such as GIA, IGI, GCAL, etc. In addition, you will receive an authorized and trustworthy report on the grading of your diamond.
