About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG593372540 or 593372540. Listed at 8 retailers as of November 1, 2026, with prices from €311 to €1,065, a €754 spread on the same certified stone. MOH London lists it at €1,065. 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.
