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 $671 to $2,990, a $2,320 spread on the same certified stone. MOH London lists it at $2,990. 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.
