About this 1.64ct lab-grown oval diamond

This 1.64ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833604231 or 833604231. Listed at 7 retailers, with prices from $608 to $3,390 at Brilliant Earth, a $2,782 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.
