About this 1.55ct lab-grown oval diamond

This 1.55ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG779652821 or 779652821. Listed at 25 retailers, with prices from $508 to $2,659 at MOH London, a $2,151 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.
