October has two wonderfully colorful birthstones: opal and tourmaline. Opal is loved for the way colors dance across its surface, while tourmaline comes in a huge range of shades, from fresh green and pink to rich blue and violet. Either one makes October a fun month for gemstone lovers.
Opal: little flashes of color
Precious opal can show a shifting rainbow of color called play-of-color. Those bright flashes come from the way light interacts with its natural internal structure. Some opals have a pale background, others are darker, and the colors can appear as tiny sparks or broad ribbons.
There are also beautiful opals without that rainbow effect, including pink and other common opals. Their lovely body color is part of the appeal.
Tourmaline: almost every shade
Tourmaline is another colorful choice, with pink and green among its most familiar varieties. Some crystals contain two colors together, creating combinations that look especially distinctive in jewelry. Transparent tourmaline is often faceted to show off its brightness and color.
A little meaning and care
Opal has traditionally been linked to hope and imagination, while tourmaline is associated with creativity and personal expression. Their individual appearances make them thoughtful birthday gifts, especially for someone who loves color.
For care, wipe both gently and store jewelry separately. Because opal varieties have different needs, avoid prolonged soaking and strong heat; mild handling is always a good starting point. Tourmaline also benefits from gentle cleaning and protection from hard knocks.
