About this 11.34ct lab-grown cushion diamond

This 11.34ct lab-grown cushion sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG670445377 or 670445377. Listed at 14 retailers as of October 26, 2026, with prices from $2,278 to $23,548, a $21,270 spread on the same certified stone. Brilliant Earth lists it at $23,548. 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.
