About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831680065 or 831680065. Listed at 13 retailers as of November 1, 2026, with prices from $406 to $2,917, a $2,511 spread on the same certified stone. Helzberg Diamonds lists it at $2,917. 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.
