About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5553601301. Listed at 19 retailers as of November 2, 2026, with a 104% 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.
