This 3.01ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG445061807 or 445061807. Listed at 6 retailers as of October 31, 2026, with prices from €1,772 to €10,455, a €8,683 spread on the same certified stone. MOH London lists it at €10,455. 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.
