Indicolite and Rubellite Ring

Indicolite – a captivating blue variety of the tourmaline mineral, belonging to the large borosilicate group. It is renowned for its rich hues, ranging from deep indigo-blue to vibrant blue-green. Its profound color can sometimes resemble aquamarine or the famous Paraiba tourmaline, yet Indicolite possesses its own unique character and beauty.

The name "Indicolite" originates from the indigo color, accurately conveying the characteristic blue hue of this precious gemstone. Some specimens can exhibit astonishing variations, including zones of yellowish or pinkish tints, or even white bands, which adds to their individuality and collector's value. This relatively rare member of the tourmaline group is mined in a limited number of locations worldwide.

The most famous deposits are found in Brazil, Nigeria, Mozambique, Afghanistan, and the USA. Indicolite typically forms in granitic pegmatites, but it can also be found as rounded pebbles in alluvial deposits, where it ends up as a result of erosion.

Due to its appealing appearance, rarity, and good hardness, Indicolite is highly prized by both mineral collectors and jewelers. It lends itself beautifully to cutting in various shapes, without losing its luster and depth of color. Exquisite jewelry pieces – rings, pendants, earrings, and necklaces – are crafted from Indicolite, highlighting its natural elegance.

Tourmaline is not a single mineral but a complex group of borosilicate minerals, captivating with an incredible diversity of colors and shades. From deep black (schorl) to vibrant pink (rubellite), rich blue (indicolite), and green (verdelite), and sometimes even combining several colors in one crystal (polychrome, or "watermelon" tourmalines) – the palette of this stone is boundless. Its name comes from the Sinhalese word "turamali," meaning "stone of mixed colors," perfectly describing its unique characteristic.

Since ancient times, tourmaline has been prized for its exceptional beauty and versatility. It forms primarily in granitic pegmatites and metamorphic rocks, with deposits found worldwide, including Brazil, Afghanistan, the USA, Madagascar, and various African countries. Thanks to its significant hardness and attractive vitreous luster, tourmaline is a popular and valuable gemstone widely used in jewelry.

Beyond its aesthetic appeal, tourmaline exhibits interesting physical properties, such as piezoelectric and pyroelectric effects – the ability to generate an electrical charge under mechanical pressure or temperature change. These properties are linked to its complex, asymmetric crystal structure.

Tourmaline is a sought-after specimen for mineral collectors due to its variety of forms and colors, and an excellent choice for creating original and vibrant jewelry pieces that highlight nature's astonishing artistry.
