About this 2.09ct natural round diamond

This 2.09ct natural round sits in the two to three carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by GIA. Listed at 5 retailers as of November 4, 2026, with a relatively tight 24% 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.
