About this 5.16ct natural round diamond

This 5.16ct natural round sits in the over five carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 836642405. Listed at 2 retailers as of November 4, 2026, with a relatively tight 10% spread, which is unusual at this carat range and suggests competitive pricing across the listings. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
