November Birthstone - Topaz and Citrine

Topaz

Topaz is a gemstone available in a rich rainbow of colors. Prized for several thousand years in antiquity, all yellow gems in antiquity were called topaz. Often confused with citrine quartz (yellow) and smoky quartz (brown), quartz and topaz are separate and unrelated mineral species. The most prized color of topaz is called Imperial topaz after the Russian Czars of the 1800s and features a magnificent orange body color with pinkish undertones. Topaz also comes in yellow, pink, purple, orange, and the many popular blue tones.

Citrine

Citrine, the other birthstone for November is known as the "healing quartz". This golden gemstone is said to support vitality and health while encouraging and guiding hope, energy and warmth within the wearer. Citrine can be found in a variety of shades ranging from pastel yellow to dark brownish orange. It is one of the most affordable of gemstones and plentiful in nature. Citrine is found most frequently in Brazil, Bolivia, and Spain.

October Birthstone - 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.
