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 very-good cut grade and certified by IGI LG665409007 or 665409007. Listed at 20 retailers as of November 1, 2026, with prices from $1,412 to $5,550, a $4,138 spread on the same certified stone. MOH London lists it at $5,550. 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.
