This 3.12ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG737542365 or 737542365. Listed at 3 retailers as of October 30, 2026, with prices from £4,112 to £4,933, a £821 spread on the same certified stone. Kay Jewelers lists it at £4,933. 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.
