This 0.91ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG650478723 or 650478723. Listed at 10 retailers as of October 29, 2026, with prices from $434 to $1,510, a $1,076 spread on the same certified stone. Brilliant Earth lists it at $1,510. 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.
