About this 3.7ct natural round diamond

This 3.7ct natural round sits in the three to five carat band, graded H colour (near-colourless) and I1 clarity (included), with a top-tier cut grade and certified by GIA 2474072685. Listed at 10 retailers as of October 31, 2026, with a relatively tight 5% 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.
