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 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.
