This 1.39ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG555298834 or 555298834. Listed at 11 retailers as of November 4, 2026, with prices from €177 to €1,042, a €865 spread on the same certified stone. Brilliant Earth lists it at €1,042. 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.
