About this 1.2ct natural asscher diamond

This 1.2ct natural asscher sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558072901. Listed at 10 retailers as of November 5, 2026, with prices from £2,185 to £4,287, a £2,102 spread on the same certified stone. NZ Jewellers lists it at £4,287. 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.
