This 3ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG673412894 or 673412894. Listed at 3 retailers as of November 1, 2026, with prices from €747 to €1,698, a €951 spread on the same certified stone. Rare Carat lists it at €1,698. 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.
