About this 1.45ct lab-grown cushion diamond

This 1.45ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG780661400 or 780661400. Listed at 6 retailers, with prices from $496 to $2,940 at Brilliant Earth, a $2,444 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.
