About this 0.91ct lab-grown cushion diamond

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 26, 2026, with prices from $618 to $2,047, a $1,429 spread on the same certified stone. MOH London lists it at $2,047. 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.
