About this 1.02ct natural asscher diamond

This 1.02ct natural asscher sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1377879149. Listed at 6 retailers as of November 2, 2026, with prices from £2,079 to £2,805, a £726 spread on the same certified stone. Yorxs lists it at £2,805. 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.
