This 0.85ct 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 LG816658194 or 816658194. Listed at 16 retailers as of November 3, 2026, with prices from £364 to £2,290, a £1,925 spread on the same certified stone. MOH London lists it at £2,290. 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.
