About this 2.5ct natural round diamond

This 2.5ct natural round sits in the two to three carat band, graded G colour (near-colourless) and I1 clarity (included), with a top-tier cut grade and certified by GSI. Listed at a single retailer as of October 26, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
