About this 1.64ct natural round diamond

This 1.64ct natural round sits in the one-and-a-half to two carat band, graded F colour (colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 2235788198. Listed at 4 retailers as of November 1, 2026, with a relatively tight 7% 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.
