This 0.92ct lab-grown oval 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 LG830623921 or 830623921. Listed at 20 retailers as of October 29, 2026, with prices from £128 to £1,014, a £885 spread on the same certified stone. Helzberg Diamonds lists it at £1,014. 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.
