About this 1.03ct natural asscher diamond

This 1.03ct 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. Listed at 3 retailers as of October 31, 2026, with prices from €2,351 to €2,848, a €497 spread on the same certified stone. Blue Nile lists it at €2,848. 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.
