This 15.12ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG764630441 or 764630441. Listed at 14 retailers as of November 2, 2026, with prices from $4,966 to $36,653, a $31,687 spread on the same certified stone. Brilliant Earth lists it at $36,653. 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.
