About this 3.51ct natural round diamond

This 3.51ct natural round sits in the three to five carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade and certified by GIA 2557399420. Listed at 14 retailers as of October 30, 2026, with a relatively tight 25% 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.
