This 0.79ct 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 LG816658196 or 816658196. Listed at 18 retailers as of November 2, 2026, with prices from £236 to £1,395, a £1,159 spread on the same certified stone. Diamond Exchange Canada lists it at £1,395. 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.
