This 3.18ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG526272374 or 526272374. Listed at 12 retailers as of October 29, 2026, with prices from €903 to €2,857, a €1,954 spread on the same certified stone. MOH London lists it at €2,857. 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.
