About this 1.69ct lab-grown cushion diamond

This 1.69ct lab-grown cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG530226710 or 530226710. Listed at 7 retailers as of October 29, 2026, with prices from €415 to €1,198, a €783 spread on the same certified stone. MOH London lists it at €1,198. 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.
