About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 5192120033. Listed at 4 retailers as of October 30, 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.
