About this 1.25ct natural radiant diamond

This 1.25ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included) and certified by GIA 6431007344. Listed at a single retailer as of November 6, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
