About this 1.57ct lab-grown cushion diamond

This 1.57ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG737565888 or 737565888. Listed at 18 retailers as of October 30, 2026, with prices from $552 to $3,534, a $2,982 spread on the same certified stone. Brilliant Earth lists it at $3,534. 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.
