October’s Birthstones: Opal and Tourmaline

We’re well into October, well into the fall, and the holidays are upon us! Before we dive into next month and gearing up for Thanksgiving, we’re thinking about October’s birth stones, which are two of our favorites: opal and tourmaline.


Opal’s country of origin is Australia. According to American Gem Society, “Seasonal rains soaked the parched outback, carrying silica deposits underground into cracks between layers of rock. When the water evaporated, these deposits formed opal. Sometimes, silica seeped into spaces around wood, seashells and skeletons, resulting in opalized fossils.” This stone is also mined in Mexico, Brazil, Honduras, among other places, such as a couple different parts of the United States.

Take extra care when wearing opal, as it can possibly crack under extreme temperatures, dehydration, or direct light.


According to American Gem Society, “The name “tourmaline” comes from the Sinhalese words tura mali, which mean “stone of mixed colors.” As its name implies, tourmaline stands apart from other gems with its broad spectrum of colors in every shade of the rainbow.” It is mined in Brazil, Sri Lanka, Nigeria, among other places, such as California. Tourmaline is beautiful due to its complex colors, and it makes for some really wonderful pieces of jewelry.

Below are some of the opal and tourmaline pieces we currently have available from Deville Fine Jewelry & Diamonds.
