About this 1.4ct lab-grown cushion diamond

This 1.4ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830620145 or 830620145. Listed at 8 retailers as of October 29, 2026, with prices from $362 to $2,729, a $2,367 spread on the same certified stone. Brilliant Earth lists it at $2,729. 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.
