About this 1ct lab-grown asscher diamond

This 1ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG601390080 or 601390080. Listed at 13 retailers as of November 2, 2026, with prices from £111 to £1,029, a £917 spread on the same certified stone. MOH London lists it at £1,029. 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.
