About this 3.5ct natural round diamond

This 3.5ct natural round sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by IGI 790691806. Listed at 6 retailers as of November 1, 2026, with a relatively tight 15% 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.
