This 0.75ct lab-grown cushion 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 LG816658274 or 816658274. Listed at 16 retailers as of October 29, 2026, with prices from £316 to £1,628, a £1,313 spread on the same certified stone. MOH London lists it at £1,628. 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.
