About this 1.5ct lab-grown cushion diamond

This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG617427794 or 617427794. Listed at 6 retailers as of October 29, 2026, with prices from $500 to $1,497, a $997 spread on the same certified stone. MOH London lists it at $1,497. 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.
