About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG817610884 or 817610884. Listed at 15 retailers as of October 29, 2026, with prices from $492 to $2,153, a $1,661 spread on the same certified stone. MOH London lists it at $2,153. 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.
