About this 10.57ct natural radiant diamond

This 10.57ct natural radiant sits in the over five carat band, graded FANCY colour (tinted) and SI2 clarity (slightly-included) and certified by GIA 1182258434. Listed at a single retailer as of October 30, 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.
