About this 1.06ct lab-grown cushion diamond

This 1.06ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG500148308 or 500148308. Listed at 7 retailers as of October 29, 2026, with prices from €226 to €1,056, a €830 spread on the same certified stone. MOH London lists it at €1,056. 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.
