About this 15.12ct lab-grown cushion diamond

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 $4,948 to $40,035, a $35,087 spread on the same certified stone. Brilliant Earth lists it at $40,035. 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.
