This 1.3ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG834609826 or 834609826. Listed at 8 retailers as of October 30, 2026, with prices from £231 to £1,829, a £1,598 spread on the same certified stone. Do Amore Diamonds lists it at £1,829. 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.
