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.

Our natural diamonds are meticulously selected to ensure a superior cut grade from Good to Excellent. We are committed to providing you with beautifully crafted diamonds that shine with exceptional luster and sparkle. Vesirio natural diamonds meet the internationally recognized standards for cut quality as described below:

Carat 0.30 - 0.95 ct 1.00 - 1.99 ct 2.000 ct and above

Cut Excellent
Excellent -

Very Good
Excellent - Good
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 Vesirio natural diamonds falls between D (Colorless) to J (Near Colorless).

Color D - J

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.
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 IF (Internally Flawless) to SI1 (Slightly Included)

IF (Internally Flawless): exhibit pristine clarity, free from internal inclusions when viewed under 10x magnification.

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.
