About this 3.55ct lab-grown oval diamond

This 3.55ct 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 LG768632246 or 768632246. Listed at 14 retailers, with prices from $1,902 to $17,960 at Brilliant Earth, a $16,058 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.
