About this 1.09ct natural asscher diamond

This 1.09ct natural asscher sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2151903973. Listed at 7 retailers as of October 28, 2026, with prices from €4,238 to €5,729, a €1,490 spread on the same certified stone. Jared lists it at €5,729. 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.
