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 15 retailers as of October 28, 2026, with prices from $3,542 to $28,660, a $25,118 spread on the same certified stone. Brilliant Earth lists it at $28,660. 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.
