About this 5.18ct natural round diamond

This 5.18ct natural round sits in the over five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by GIA 5221567953. Listed at 5 retailers as of October 29, 2026, with a relatively tight 14% 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.
