About this 1.28ct lab-grown cushion diamond

This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605341761 or 605341761. Listed at 10 retailers as of November 1, 2026, with prices from €201 to €981, a €780 spread on the same certified stone. MOH London lists it at €981. 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.
