About this 4.05ct lab-grown radiant diamond

This 4.05ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG662415764 or 662415764. Listed at 18 retailers, with prices from $1,918 to $9,431 at Novita Diamonds, a $7,513 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.
