Although sapphires come in many colors - blue is perhaps it's most beloved.
Many legends, mythologies, and religions reference the occult properties associated with sapphire - from a belief in its ability to cure tumours, to impart wisdom, peacefulness, and impart divine favor.
Ancient Persians believed that the Earth rested on an enormous Sapphire and that the reflection from this Sapphire was what gave the sky its blue color.
The beautiful blue that ranges from very pale to cornflower to deep indigo comes from the presence of Iron and Titanium.
