About this 1.03ct lab-grown cushion diamond

This 1.03ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG722515599 or 722515599. Listed at 16 retailers as of October 29, 2026, with prices from £296 to £1,289, a £994 spread on the same certified stone. MOH London lists it at £1,289. 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.
