This 1.54ct 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 very-good cut grade and certified by IGI LG839680534 or 839680534. Listed at 11 retailers as of October 31, 2026, with prices from $497 to $2,120, a $1,623 spread on the same certified stone. Brilliant Earth lists it at $2,120. 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.
