About this 2.81ct lab-grown radiant diamond

This 2.81ct lab-grown radiant sits in the two to three carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG726520915 or 726520915. Listed at 21 retailers as of November 2, 2026, with a 438% 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.
