About this 0.81ct natural radiant diamond

This 0.81ct natural radiant sits in the just-under-one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI 291753806. Listed at 2 retailers as of November 6, 2026, with a relatively tight 4% 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.
