About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG677539348 or 677539348. Listed at 3 retailers as of October 31, 2026, with prices from €870 to €1,221, a €351 spread on the same certified stone. Kay Jewelers lists it at €1,221. 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.
