About this 0.76ct lab-grown cushion diamond

This 0.76ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830621836 or 830621836. Listed at 12 retailers as of November 3, 2026, with prices from £309 to £1,340, a £1,031 spread on the same certified stone. MOH London lists it at £1,340. 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.
