0.30ct F SI2 Round Natural Diamond

About this 0.3ct natural round diamond

This 0.3ct natural round sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 5563432668. Listed at 17 retailers as of October 26, 2026, with a relatively tight 5% 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.
