About this 1.05ct lab-grown cushion diamond

This 1.05ct 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 LG840634725 or 840634725. Listed at 14 retailers as of October 29, 2026, with prices from $624 to $2,097, a $1,473 spread on the same certified stone. Brilliant Earth lists it at $2,097. 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.
