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 17 retailers as of November 1, 2026, with prices from $2,812 to $22,305, a $19,493 spread on the same certified stone. Brilliant Earth lists it at $22,305. 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.
