About this 1ct natural asscher diamond

This 1ct 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 2557178214. Listed at 16 retailers as of November 5, 2026, with prices from £1,395 to £3,161, a £1,766 spread on the same certified stone. NZ Jewellers lists it at £3,161. 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.
