This 1.4ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG596324317 or 596324317. Listed at 4 retailers as of October 28, 2026, with prices from €1,289 to €1,770, a €481 spread on the same certified stone. Kay Jewelers lists it at €1,770. 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.
