About this 1.55ct natural round diamond

This 1.55ct natural round sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI. Listed at 2 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.
