Natural Blue Sapphire 4.43 Carats Set in 18K White Gold and Diamond Ring

Titanic Beauty. The blue sapphire is the most majestic and traditional of all colored gems and has been prized for centuries for its beauty.
In cultures spanning India, China, across Asia to Europe, blue sapphires were set into the crowns, jewelry, sacred objects, and weapons of rulers and warriors because the stones were believed to deflect harm from enemies. 
This belief persists today. In some parts of the world, blue sapphire is embedded into the foundation of a new building before construction begins, to welcome good luck.
We'd rather see it on you.
This specific stone is untreated, a heroic, deep-sea blue set amidst the fire of white diamonds.
