Complete crystal database

Returns all 54 crystals in the database sorted alphabetically. Each entry includes chakra associations, elemental correspondences, Vedic and Western planetary assignments, healing properties, origins, affirmations, and safety cautions. Vedic correspondences are strictly separated: 'navaratna' (classical primary gem), 'uparatna' (substitute gem; the description says when a substitute is modern rather than classical), or 'none_classical' (no Vedic gem use).
