October Birthstones: Opal and Tourmaline

Opal: Opal dazzles with a play-of-color—flashes of red, orange, blue, and green that dance across its milky or transparent body as it moves.

Tourmaline: Tourmaline occurs in a kaleidoscope of hues—from vibrant pinks and greens to deep blues and bi-color combinations—occasionally showing strong color zoning.
