About this 1.25ct lab-grown oval diamond

This 1.25ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG811647464 or 811647464. Listed at 20 retailers, with prices from $518 to $3,700 at Brilliant Earth, a $3,182 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.
