About this 2.66ct lab-grown radiant diamond

This 2.66ct 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 stated by the retailer rather than the lab and certified by GIA 6472681343. Listed at 21 retailers as of November 1, 2026, with a 498% 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.
