Opal & Tourmaline
Opal is known for its 'play of color' - flashes of spectral hues that shift as the stone moves. This phenomenon results from ordered silica spheres diffracting light. Australia is a historically important source, while other deposits include Ethiopia, Mexico, and Brazil.

The lists agree, with additions: Opal is the older October stone. Tourmaline was added in 1952, largely because a transparent, faceted gem suited modern ring settings better than opal.

Two signs overlap October
Libra can begin on September 22 or September 23 depending on the year. Scorpio can begin on October 22 or October 23 depending on the year. A sign starts when the Sun reaches its point on the ecliptic, and that moment drifts by up to about a day across the leap-year cycle, so a birthday on a boundary day cannot be settled from a date table alone.
Astrology note: These are conventional tropical date ranges. Traits and compatibility are interpretations within astrology, not measured outcomes.

The year—and its New Year boundary—matters
A month alone cannot produce an exact Chinese zodiac animal. January and February birthdays can belong to the preceding zodiac year until Chinese New Year occurs.
