About this 1.22ct lab-grown radiant diamond

This 1.22ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG743509184 or 743509184. Listed at 21 retailers as of November 4, 2026, with a 683% 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.
