About this 1.26ct lab-grown asscher diamond

This 1.26ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG728521733 or 728521733. Listed at 8 retailers as of November 5, 2026, with prices from £325 to £836, a £511 spread on the same certified stone. MOH London lists it at £836. 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.
