About this 0.99ct lab-grown radiant diamond

This 0.99ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825631917 or 825631917. Listed at 20 retailers as of October 30, 2026, with a 597% 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.
