About this 15.1ct lab-grown cushion diamond

This 15.1ct 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 LG778692474 or 778692474. Listed at 16 retailers as of November 1, 2026, with prices from $4,058 to $17,400, a $13,342 spread on the same certified stone. With Clarity lists it at $17,400. 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.
