About this 1.42ct lab-grown cushion diamond

This 1.42ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830620295 or 830620295. Listed at 13 retailers as of October 30, 2026, with prices from $332 to $2,373, a $2,040 spread on the same certified stone. Helzberg Diamonds lists it at $2,373. 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.
