About this 1ct lab-grown cushion diamond

This 1ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG620421921 or 620421921. Listed at 14 retailers, with prices from $200 to $2,140 at Brilliant Earth, a $1,940 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.
