Cassiterite meaning: The name Cassiterite comes from the Greek word, kassiteros, which means tin.  There is also a Phoenician word, Cassiterid, which is about Ireland and Great Britain.  This may be because tin came from these islands in ancient times. 

Cassiterite metaphysical properties: This is the crystal to hold to encourage alignment with your intuition, clairvoyance, and dreams that reveal the future.  This particularly applies to individuals who have previously struggled to be good, to be perfect, to always choose right from wrong.  Cassiterite just naturally aligns such an individual with a higher vibration of self-acceptance and tolerance that opens up their already highly-intelligent mind to the wisdom of the Divine Feminine.
