About this 1.39ct natural round diamond

This 1.39ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and I1 clarity (included), with a standard cut grade and certified by GIA 2225484611. Listed at 2 retailers as of November 1, 2026, with a relatively tight 8% 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.
