About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included) and certified by GIA 5201825329. 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.
