About this 15.38ct natural round diamond

This 15.38ct natural round sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2235170768. Listed at 3 retailers as of October 27, 2026, with a relatively tight 12% 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.
