About this 3.21ct natural round diamond

This 3.21ct natural round sits in the three to five carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade and certified by GIA 2233997698. Listed at 2 retailers as of November 2, 2026, with a relatively tight 6% 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.
