About this 1.67ct lab-grown oval diamond

This 1.67ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI. Listed at 4 retailers, with prices from $438 to $3,214 at Blue Nile, a $2,776 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.
