About this 5.09ct lab-grown radiant diamond

This 5.09ct lab-grown radiant sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754595505 or 754595505. Listed at 31 retailers as of October 30, 2026, with prices from €8,135 to €38,487, a €30,353 spread on the same certified stone. With Clarity lists it at €38,487. 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.
