About this 4.26ct lab-grown radiant diamond

This 4.26ct 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 LG772627323 or 772627323. Listed at 24 retailers, with prices from $4,881 to $25,984 at With Clarity, a $21,103 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.
