About this 1.33ct lab-grown radiant diamond

This 1.33ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG623421838 or 623421838. Listed at 24 retailers as of October 30, 2026, with prices from €284 to €1,969, a €1,685 spread on the same certified stone. Brilliant Earth lists it at €1,969. 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.
