About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 25687004. Listed at 2 retailers as of October 29, 2026, with a relatively tight 11% 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.
