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 FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831690477 or 831690477. Listed at 10 retailers as of October 30, 2026, with prices from $546 to $2,598, a $2,052 spread on the same certified stone. Helzberg Diamonds lists it at $2,598. 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.
