A mineral form of fluorite or calcium fluoride; also, a person or thing having affinity with another.
From 'affinity,' possibly influenced by Latin mineralogical nomenclature. The term has been used both for a mineral species and metaphorically for related entities.
Gemstone dealers and mineralogists recognize affinite as a specific variant of fluorite, but the word also works metaphorically—your 'affinites' are those things naturally drawn to you!
