This 5.15ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821652543 or 821652543. Listed at 3 retailers as of October 31, 2026, with prices from €4,982 to €7,161, a €2,179 spread on the same certified stone. Kay Jewelers lists it at €7,161. 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.
