About this 1.09ct natural round diamond

This 1.09ct natural round sits in the classic one-carat band, graded K colour (faint-tinted) and I2 clarity (included), with a very-good cut grade and certified by IGI GT13556206. Listed at 3 retailers as of November 4, 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.
