About this 1.05ct lab-grown cushion diamond

This 1.05ct 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 LG789611535 or 789611535. Listed at 15 retailers as of October 26, 2026, with prices from €340 to €1,514, a €1,175 spread on the same certified stone. MOH London lists it at €1,514. 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.
