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 prices from $316 to $2,236, a $1,920 spread on the same certified stone. Rare Carat lists it at $2,236. 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.
