About this 1.04ct lab-grown asscher diamond

This 1.04ct lab-grown asscher sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG728521731 or 728521731. Listed at 8 retailers as of October 29, 2026, with prices from £266 to £839, a £573 spread on the same certified stone. MOH London lists it at £839. 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.
