Schorl

Buy natural tourmaline in our shop

The most common species of tourmaline is schorl, a sodium iron endmember of the tourmaline group, which may account for 95% or more of all tourmaline found in nature. Schorl is particularly known for its deep black color and is often used in jewelry as well as for its purported metaphysical properties, such as protection from negative energy. The mineral schorl has a rich history, with its name being used as early as the 1400s. The village now known as Zschorlau in Saxony, Germany, was originally called “Schorl” or similar variations, and was located near a tin mine where black tourmaline, alongside cassiterite, was discovered.

The earliest documented description of the mineral named “schürl” was written by Johannes Mathesius in 1562, in his work titled “Sarepta oder Bergpostill.” Mathesius described the occurrence of schorl in various tin mines in the Saxony Ore Mountains. The mineral was also known by several other names, including “Schurel,” “Schörle,” and “Schurl,” during the 16th century. By the 18th century, “Schörl” became the most commonly used term in the German-speaking regions. In English-speaking countries, the names “shorl” and “shirl” were used in the 18th century, while in the 19th century, the terms “common schorl,” “schörl,” “schorl,” and “iron tourmaline” were adopted.

Tourmaline Stone: A Versatile Semi-Precious Gemstone

Tourmaline is a crystalline boron silicate mineral that can contain a variety of trace elements, such as aluminum, iron, magnesium, sodium, lithium, and potassium. Classified as a semi-precious gemstone, tourmaline is notable for its wide range of colors, including black, pink, green, blue, and even colorless varieties. The diverse composition of tourmaline is what gives rise to its varied color palette, making it a popular choice among gem collectors and jewelry enthusiasts.

Black tourmaline, or schorl, is particularly valued for its grounding properties, and is believed to provide protection from electromagnetic radiation and negative energies. This variety is commonly found in metamorphic and igneous rocks, where it forms as a result of mineralogical changes during the rock’s formation. Schorl is frequently utilized in crystal healing practices and is considered a powerful stone for those seeking grounding and emotional stability.

Etymology of Tourmaline

The name “tourmaline” is derived from the Sinhalese word “thoramalli,” which refers to a group of gemstones found in Sri Lanka. This etymology is supported by various authoritative sources, including the Madras Tamil Lexicon and the Oxford English Dictionary. The Tamil term “tuvara-malli” also shares its roots with the Sinhalese word, indicating the shared cultural history behind the gemstone’s name.

Throughout history, tourmaline has been admired for its beauty and versatility. In particular, black tourmaline has been appreciated for its striking appearance and its perceived ability to repel negative energy. This variety has been used for centuries in both decorative and spiritual contexts, and it remains highly sought after for its unique properties.

Enhancement and Treatment of Tourmaline

Like many gemstones, tourmaline can undergo various treatments to enhance its appearance. Pink to red tourmalines, for example, can be heat treated to lighten dark hues or improve their overall vibrancy. Stones containing manganese may also be irradiated with gamma rays or electrons to intensify their pink coloration. These treatments are often subtle and do not usually affect the value of the gemstone, as they are considered standard industry practices.

Certain varieties of tourmaline, such as rubellite and Brazilian Paraíba, may be improved through laboratory techniques, especially if the stones contain numerous inclusions. A certificate from a gemological laboratory can attest to the type of treatment the stone has undergone, providing transparency to buyers. It is worth noting that treated stones, particularly Paraíba tourmaline, may be valued less than untreated, naturally colored specimens of similar quality.
