This 1.28ct lab-grown asscher 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 LG750516737 or 750516737. Listed at 4 retailers as of October 30, 2026, with prices from £872 to £1,217, a £344 spread on the same certified stone. Kay Jewelers lists it at £1,217. 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.
