October Birthstone

Traditionally, a birthstone is associated with each month of the year. For example, the birthstone for January is a garnet, while lucky babies born in April get a diamond as their birthstone.

The origin of birthstones is believed to date back to the breastplate of Aaron which contained twelve gemstones representing the twelve tribes of Israel. The current list dates back to 1912 with only one addition since then – the tanzanite was added to December.

There are numerous legends and myths about birthstone healing powers and their therapeutic influence. According to these legends, wearing a gemstone during its assigned month heightened its healing powers. For the full effect, individuals needed to own all twelve and alternate them monthly.

October is another month with two birthstone choices – Tourmaline and Opal.

Tourmaline

Tourmaline has become a favorite gemstone among jewelry designer, and gem collectors the world over. Since it is available in a wide variety of colors, it is ideally suited to almost anyone's taste. Tourmaline also is known for displaying several colors in the same gemstone.  These bi-color or tri-color gems are formed in many combinations; gemstones with clear color distinctions are highly prized.  One multi-color variety is known as watermelon tourmaline, and features green, pink, and white colors bands; to resemble its namesake, the gemstone is cut into thin slices having a pink center, white ring, and green edge. 

Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the USA.

Opal

The name opal derives from the Greek Opallos, meaning "to see a change (of color)."  Opals range in color from milky white to black with flashes of yellow, orange, green, red, and blue. An opal's beauty is the product of contrast between its color play and its background.  Opal is a formation of non-crystalline silica gel that seeped into crevices in the sedimentary strata. Through time and nature's heating and molding processes, the gel hardened into the form of opals. The opal is composed of particles closely packed in spherical arrangements. When packed together in a regular pattern, a three-dimensional array of spaces are created that give opal its radiance.
