This 1.56ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG523291258 or 523291258. Listed at 15 retailers as of October 30, 2026, with prices from £243 to £1,933, a £1,690 spread on the same certified stone. Do Amore Diamonds lists it at £1,933. 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.
