About this 4.02ct lab-grown radiant diamond

This 4.02ct 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 LG754594956 or 754594956. Listed at 25 retailers, with prices from $3,823 to $23,336 at With Clarity, a $19,513 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.
