About this 5.03ct natural radiant diamond

This 5.03ct natural radiant sits in the over five carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 2145173201. Listed at 4 retailers as of October 31, 2026, with a relatively tight 14% 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.
