About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG620417166 or 620417166. Listed at 13 retailers as of November 1, 2026, with prices from $489 to $2,435, a $1,946 spread on the same certified stone. Rare Carat lists it at $2,435. 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.
