About this 1ct lab-grown asscher diamond

This 1ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG524244824 or 524244824. Listed at 15 retailers as of October 29, 2026, with prices from £105 to £610, a £505 spread on the same certified stone. MOH London lists it at £610. 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.
