Happy birthday to all the October babies out there! October features two very unique and different birthstones. Tourmaline and Opal, two of the most gorgeous and diverse birthstones make beautiful and vibrant jewelry. Let’s explore them individually:
The first October birthstone is tourmaline. It has become a favorite gemstone among jewelry designers, 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.
The name opal derives from the Greek Opallos, meaning “to see a change (of color).” This October birthstone ranges 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.
