About this 0.8ct natural radiant diamond

This 0.8ct natural radiant sits in the just-under-one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558781391. Listed at 6 retailers as of October 29, 2026, with a 91% 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.
