About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 2191525964. Listed at 4 retailers as of November 5, 2026, with a relatively tight 10% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
