About this 5.04ct natural round diamond

This 5.04ct natural round sits in the over five carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA. Listed at 9 retailers as of November 6, 2026, with a relatively tight 20% 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.
