This 1.22ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831687283 or 831687283. Listed at 20 retailers as of October 27, 2026, with prices from £139 to £810, a £670 spread on the same certified stone. MOH London lists it at £810. 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.
