About this 4.09ct lab-grown radiant diamond

This 4.09ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG754595534 or 754595534. Listed at 21 retailers, with prices from $3,886 to $17,806 at With Clarity, a $13,920 spread on the same certified stone. 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.
