About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2378907307. Listed at 16 retailers as of November 1, 2026, with prices from £1,662 to £2,403, a £740 spread on the same certified stone. Yorxs lists it at £2,403. 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.
