This 1.31ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG770637399 or 770637399. Listed at 20 retailers as of October 28, 2026, with prices from £169 to £1,082, a £914 spread on the same certified stone. Brilliant Earth lists it at £1,082. 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.
