This 6.51ct 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 LG841638735 or 841638735. Listed at 13 retailers as of October 27, 2026, with prices from $2,835 to $11,510, a $8,675 spread on the same certified stone. Taylor and Hart lists it at $11,510. 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.
