About this 1.04ct lab-grown asscher diamond

This 1.04ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG830637359 or 830637359. Listed at 17 retailers as of October 28, 2026, with prices from £144 to £831, a £686 spread on the same certified stone. MOH London lists it at £831. 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.
