About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded J colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5406135010. Listed at 12 retailers as of November 2, 2026, with a 57% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
