About this 1.6ct lab-grown cushion diamond

This 1.6ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG551291037 or 551291037. Listed at 5 retailers as of October 29, 2026, with prices from €379 to €1,055, a €676 spread on the same certified stone. MOH London lists it at €1,055. 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.
