What is Rubellite Tourmaline?

Elbaite is a sodium and lithium aluminum boron silicate with the chemical formula Na(Li1.5Al1.5)Al6Si6O18(BO3)3(OH)4. It belongs to the six-membered ring cyclosilicate subgroup of the tourmaline family.

Formation and Mineral Associations

Rubellite typically forms in igneous and metamorphic rocks, often in association with minerals such as lepidolite, microcline, and spodumene in granite pegmatites. It can also occur with andalusite and biotite in schist, as well as with molybdenite and cassiterite in massive hydrothermal deposits.

Allochromatic Properties

Elbaite, including rubellite, is an allochromatic mineral, meaning its color is influenced by trace impurities. This characteristic allows it to exhibit a wide range of colors, from pink and red to multicolored zonation. In some cases, microscopic acicular inclusions within elbaite crystals create a cat’s eye effect when cut into cabochons.

Color Variations and Value

Among the elbaite colors, rubellite’s vivid pink to red hues are highly prized. Blue indicolite and green verdelite also hold significant value, but rubellite’s intense coloration and rarity make it a standout choice for collectors and jewelers alike.

The Unique Properties of Rubellite Stone

Tourmaline, including rubellite, is a crystalline boron silicate mineral that combines elements like aluminum, iron, magnesium, sodium, lithium, and potassium. Classified as a semi-precious gemstone, it comes in an impressive variety of colors, with rubellite standing out for its striking red and pink shades.

Crystal Structure

Tourmaline has a six-membered ring cyclosilicate structure and a trigonal crystal system. It typically forms as long, slender to thick prismatic crystals, often triangular in cross-section with curved, striated faces. Some specimens display asymmetrical terminations, a feature known as hemimorphism.

Piezoelectric and Pyroelectric Properties

All hemimorphic tourmaline crystals, including rubellite, are piezoelectric, meaning they can generate an electric charge when subjected to mechanical stress. Many are also pyroelectric, producing a charge in response to temperature changes. These properties make tourmaline unique not only for its aesthetic qualities but also for its scientific applications.

Rubellite vs. Other Tourmalines

What sets rubellite apart from other tourmalines is its ability to retain its vibrant color under various lighting conditions. While pink tourmaline may appear lighter or change hue depending on the light source, rubellite maintains its rich red to pinkish-red tone, adding to its allure.
