About this 1.02ct natural asscher diamond

This 1.02ct natural asscher sits in the classic one-carat band, graded D 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 €4,069 to €5,143, a €1,074 spread on the same certified stone. Blue Nile lists it at €5,143. 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.
