About this 1.1ct natural round diamond

This 1.1ct natural round sits in the classic one-carat band, graded F colour (colourless) and I1 clarity (included), with a standard cut grade and certified by GIA 2426989553. Listed at 2 retailers as of October 29, 2026, with a relatively tight 13% 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.
