About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565487301. Listed at 8 retailers as of October 31, 2026, with prices from £1,684 to £3,268, a £1,584 spread on the same certified stone. MOH London lists it at £3,268. 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.
