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 LG830623927 or 830623927. Listed at 15 retailers as of October 30, 2026, with prices from $405 to $1,925, a $1,520 spread on the same certified stone. Helzberg Diamonds lists it at $1,925. 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.
