This 1.26ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799676340 or 799676340. Listed at 5 retailers as of November 2, 2026, with prices from £293 to £770, a £478 spread on the same certified stone. MOH London lists it at £770. 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.
