This 1.27ct 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 LG585320872 or 585320872. Listed at 4 retailers as of October 31, 2026, with prices from £828 to £1,157, a £328 spread on the same certified stone. Kay Jewelers lists it at £1,157. 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.
