About this 4.01ct lab-grown radiant diamond

This 4.01ct 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 LG737578616 or 737578616. Listed at 24 retailers, with prices from $3,599 to $16,416 at With Clarity, a $12,817 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.
