About this 4ct natural radiant diamond

This 4ct natural radiant sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 15654946. Listed at 4 retailers as of November 6, 2026, with a relatively tight 13% 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.
