About this 1.98ct lab-grown cushion diamond

This 1.98ct lab-grown cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436045621 or 436045621. Listed at 6 retailers as of October 31, 2026, with prices from €967 to €5,045, a €4,078 spread on the same certified stone. MOH London lists it at €5,045. 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.
