Opal and Tourmaline -
The birthstone of August
MyBirthStone.org
Opal has a unique "play-of-color" (a shifting display of spectral hues caused by light diffracting through microscopic silica spheres). Tourmaline has the broadest color range of any gemstone family.
Opal's shifting rainbow colors stand for hope and possibility. Light and color emerge even from the darkest stone.
Pink tourmaline (rubellite) and fire opal are linked to matters of the heart, encouraging compassion and emotional connection.
