About this 11.1ct lab-grown cushion diamond

This 11.1ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG788666449 or 788666449. Listed at 18 retailers as of November 2, 2026, with prices from $1,938 to $12,021, a $10,083 spread on the same certified stone. With Clarity lists it at $12,021. 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.
