Opal
October wears every colour at once: opal, hydrated silica that diffracts light into shifting fire. Its file: imagination, inspiration, all-of-the-above — plus the most famous curse rumour in gemology, debunked below.
Story & folklore
Rome called it opalus and prized it as containing every gem's virtue; Arabic lore said opals fell in lightning. The 'unlucky' rumour is traceable: an 1829 Walter Scott novel featured a fateful opal, sales dipped, jewellers grumbled for a century — a literary review mistaken for a curse.
The honest paragraph
October's stone carries this list's cleanest debunk: the bad luck is fan fiction with a publication date. The play-of-colour is diffraction through silica spheres — real, mesmerising physics. Care is the true caution: opals hold water (5-10%) and dislike heat, dryness and knocks; the drama was always in the mineral, never the luck.
The cat's eye catches the lamp and flashes every colour: "Curses. Inventions of the unimaginative."
Birthstone meanings are tradition and story, told with affection — a lovely lens for a gift or a self-portrait, never a verdict or a promise.
