About this 1.01ct lab-grown cushion diamond

This 1.01ct 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 LG836621509 or 836621509. Listed at 15 retailers as of October 25, 2026, with prices from $279 to $1,570, a $1,291 spread on the same certified stone. Brilliant Earth lists it at $1,570. 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.
