1st chakra. This lustrous metallic crystal can be used for grounding and for protecting oneself from all physical danger, use when taking on challenging physical events such as sporting activities or when driving long distances. Metallic minerals are very reflective, they can reflect to others our true thoughts and who we really are. Cassiterite is good in relationships for its 'mirroring' quality.

Cassiterite has been the primary ore of tin since the Bronze Age first began — and remains so. It occurs in two main ways; at primary sites and as alluvial deposits. The two main primary formations — those in Bolivia and Cornwall, England — have been more or less mined out. As a result, most tin extraction is now carried out from alluvial deposits that have resulted from cassiterite being weathered out of rocks and washed into river beds over geologic time. Cassiterite occurs in several different forms, from granular to botryoidal, fibrous, concretionary, and massive, as well as in a variety of crystal geometries. It has an adamantine or greasy luster and a streak which is typically white, but sometimes brown.
