About this 2.5ct natural radiant diamond

This 2.5ct natural radiant sits in the two to three carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by HRD 260000139313. Listed at 7 retailers as of October 31, 2026, with a 63% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
