GIA-certified 4.10 carat natural round brilliant diamond in D color and VS2 clarity — the highest color grade available — offered as a loose investment-grade stone with GIA report number 731177167. This diamond is unset and ready for custom mounting.

This 4.10 carat round brilliant diamond represents one of the most coveted combinations in the fine diamond market: D color and VS2 clarity in a stone exceeding 4 carats — a specification that places it firmly in the investment-grade category recognized by diamond dealers, auction houses, and private collectors worldwide. D color is the absolute pinnacle of the GIA color grading scale, indicating a perfectly colorless stone with no detectable color even under magnification by a trained gemologist — a quality found in fewer than 1% of all diamonds graded by GIA annually. VS2 clarity at this carat weight means inclusions are present but entirely invisible to the naked eye, ensuring that the diamond faces up as a flawless, brilliant, and visually perfect stone in any setting. Round brilliant diamonds of 4 carats and above in D/VS2 quality are consistently among the most liquid and appreciating assets in the colored stone and diamond investment markets, with strong demand from collectors, investors, and custom engagement ring buyers who seek maximum brilliance, maximum color purity, and GIA documentation they can trust.
