This 6.72ct 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 LG818630193 or 818630193. Listed at 7 retailers as of November 1, 2026, with prices from $3,194 to $15,898, a $12,704 spread on the same certified stone. Diamonds Direct lists it at $15,898. 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.
