This 6.54ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG660430090 or 660430090. Listed at 18 retailers as of October 31, 2026, with prices from $2,210 to $17,531, a $15,321 spread on the same certified stone. Brilliant Earth lists it at $17,531. 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.
