About this 1.91ct lab-grown cushion diamond

This 1.91ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG805608107 or 805608107. Listed at 9 retailers as of October 28, 2026, with prices from $402 to $1,707, a $1,305 spread on the same certified stone. Rare Carat lists it at $1,707. 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.
