This 0.92ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830620101 or 830620101. Listed at 14 retailers as of November 4, 2026, with prices from £159 to £1,217, a £1,058 spread on the same certified stone. Helzberg Diamonds lists it at £1,217. 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.
