Is a 1.02 carat round diamond big enough for an engagement ring?

At roughly 4.3 mm across, it reads as a small stone. It works well as a solitaire on a thin band or as a side stone, but it will not look like a large centerpiece.

Is D color and VVS1 clarity worth paying for?

Both are near the top of the scale, so the stone will look colorless and clean to the eye. In a stone this small, most shoppers cannot tell D from G or VVS1 from VS1 without a loupe, so you may save by stepping down a grade.

What does the IGI certificate cover?

It documents the carat weight, color, clarity, cut and measurements. Ask for the certificate number and check it on IGI's site before buying.

Is $479 a good price for this stone?

It is within the usual range for a certified 1.02 carat D VVS1 lab-grown round, not an obvious steal. Compare per-carat prices across the two stores listing it new before you commit.

Does the price include a setting or a ring?

This is a loose diamond. A setting, band and setting labor are separate costs, and Diamaura sells custom ring design as a separate service.

Our take on the 1.02 Carat ROUND D VVS1 IGI Ideal Cut

This is a loose 1.02 carat round lab-grown diamond graded D color (colorless) and VVS1 clarity, with an Ideal cut and an IGI certificate. At about 4.3 mm across, it is a small stone for its weight, so it suits a delicate solitaire or a side-stone setting rather than a large centerpiece. The best new price is $479 at Amazon as of November 5, 2026, and two stores list it new. Loose lab-grown stones in this grade range commonly sell for a few hundred dollars, so this price sits in the normal band rather than at a clear bargain.
