A Samara is an independent dry indehiscent fruit which has part of the fruit wall extended to form a wing (i.e. not a winged seed inside another type of seed pod). This is the fruit of a Maple (Acer). This is a Schizocarpic Samara, because the fruit splits into its separate Samaras.
As a talisman, Pyrite is a unique protector, drawing energy from the Earth through the physical body and into the aura creating a defensive shield against negative energies, environmental pollutants, emotional attack and physical harm.
Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear indicators exists. Pyrite's structure is analogous to galena's structure with a formula of PbS.
