The exact piece shown in the photos is the one you will receive, with a 1cm cube included for precise scale. All of our crystals are 100% genuine specimens and each comes with a Certificate of Authenticity.

Geological Background – Afghanistan’s Gemstone Deposits

Afghanistan is one of the world’s premier sources of fine gem-quality minerals, particularly Tourmaline, Kunzite, Aquamarine, Lapis Lazuli, and Quartz. The rugged mountainous terrain of the Hindu Kush and Pamir ranges is rich in granite pegmatites, where minerals crystallise under slow cooling conditions, allowing for exceptional size and clarity.

Tourmalines, including the rare Blue Indicolite variety, are often discovered in association with Quartz and other silicates within these pegmatite veins. The combination of Tourmaline with Quartz adds both scientific value and visual appeal, representing the intricate interplay of geological processes over millions of years.

Crystal Type and Mineralogical Features

Tourmaline is a complex borosilicate mineral with variable composition, expressed by the formula (Na,Ca)(Li,Mg,Al)₃Al₆(BO₃)₃Si₆O₁₈(OH,F)₄. Indicolite is the rare blue variety of Tourmaline, its colour primarily derived from trace elements such as iron and, in some cases, copper. The Quartz present in this specimen is composed of SiO₂, one of the most common and durable minerals on Earth, providing a stable crystalline matrix that enhances the overall specimen.

Key characteristics include:

• Crystal habit – Indicolite forms elongated prismatic crystals with vertical striations, often transparent to translucent.
• Colour and luster – This specimen displays deep blue tones with excellent vitreous luster, contrasting beautifully against the clear Quartz.
• Hardness – Tourmaline registers 7 to 7.5 on the Mohs scale, while Quartz measures 7, making this a durable and collectible pairing.
• Transparency – Indicolite may show areas of translucency to near transparency, particularly under strong light.

Colour and Rarity of Indicolite

Indicolite is among the rarest and most valuable Tourmaline colour varieties. Its name derives from the Latin indicum, meaning indigo blue. While Tourmaline occurs in a wide colour spectrum, blue shades are far less common and are especially sought after by both gem cutters and mineral collectors. Specimens that exhibit intense saturation and clarity are exceptionally rare, and when combined naturally with Quartz, their desirability increases further.

Geological and Collector Significance

The presence of Indicolite Tourmaline alongside Quartz highlights the unique conditions within Afghan pegmatites, where boron-rich fluids crystallise alongside silica-rich environments. Such combinations are not only visually striking but also scientifically significant, offering insights into pegmatitic mineralisation processes.

Collectors value Indicolite specimens for their rarity, beauty, and the prestige associated with their origin. Afghan Tourmalines, particularly those with vivid blue hues, are regarded as some of the finest examples available on the global market. This piece is both a mineralogical treasure and an aesthetic specimen, suitable for display in private or institutional collections.
