About this 1.2ct natural asscher diamond

This 1.2ct natural asscher sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1539509688. Listed at 17 retailers as of November 4, 2026, with prices from £1,629 to £3,674, a £2,045 spread on the same certified stone. MOH London lists it at £3,674. 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.
