About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included) and certified by GIA 2215052753. Listed at 2 retailers as of November 6, 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.
