This 6.18ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825614971 or 825614971. Listed at 12 retailers as of October 31, 2026, with prices from $2,249 to $7,588, a $5,338 spread on the same certified stone. Taylor and Hart lists it at $7,588. 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.
