About this 0.8ct natural round diamond

This 0.8ct natural round sits in the just-under-one-carat band, graded N colour (tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2437101399. Listed at 8 retailers as of November 4, 2026, with a relatively tight 17% 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.
