About this 4.06ct lab-grown oval diamond

This 4.06ct lab-grown oval 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 LG754594987 or 754594987. Listed at 22 retailers, with prices from $3,420 to $20,540 at Brilliant Earth, a $17,120 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.
