About this 1ct natural asscher diamond

This 1ct 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 5556281868. Listed at 10 retailers as of October 27, 2026, with prices from £1,043 to £3,189, a £2,146 spread on the same certified stone. NZ Jewellers lists it at £3,189. 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.
