About this 1.2ct natural asscher diamond

This 1.2ct natural asscher sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6191873949. Listed at 26 retailers as of November 5, 2026, with prices from £3,151 to £7,228, a £4,077 spread on the same certified stone. NZ Jewellers lists it at £7,228. 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.
