About this 1.07ct lab-grown cushion diamond

This 1.07ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840635106 or 840635106. Listed at 13 retailers as of October 30, 2026, with prices from $717 to $3,394, a $2,677 spread on the same certified stone. Helzberg Diamonds lists it at $3,394. 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.
