Very Rare Blue Indicolite Tourmaline with Quartz Combined Natural Crystal Specimen from Afghanistan with Certificate of Authenticity

Description

100% Genuine Indicolite Tourmaline with Quartz

This is a very rare Blue Indicolite Tourmaline with Quartz combined specimen from the renowned mineral-rich regions of Afghanistan. Indicolite, the striking blue variety of Tourmaline, is highly prized for its vibrant indigo tones and scarcity in nature. This specimen is enhanced by its natural association with Quartz, creating a beautiful contrast that highlights both minerals in their crystalline form. The exact specimen pictured is the one you will receive, shown alongside a 1cm scale cube for accurate sizing. Every crystal we supply is 100% genuine and comes with a Certificate of Authenticity.

Geological Origin – Pegmatite Deposits of Afghanistan

Afghanistan’s rugged Hindu Kush mountain ranges are among the most significant global sources for rare and collectible gemstones. The country’s pegmatite formations, intrusions of coarse-grained igneous rock, are especially famous for producing world-class crystals, including Aquamarine, Kunzite, Spodumene, and Tourmaline. Within these pegmatites, conditions of slow cooling and mineral-rich fluids allowed for the growth of large, well-formed crystals.

Indicolite Tourmaline in particular is an uncommon find, with deep blue hues deriving from trace amounts of iron within the borosilicate structure. Quartz, one of Earth’s most abundant minerals, crystallises alongside in these environments, creating dramatic natural combinations such as this specimen.

Mineralogical Characteristics

• Tourmaline Group: A complex borosilicate mineral family, Tourmaline is known for its wide spectrum of colours. Indicolite is the rare blue variety.
• Chemical Formula: (Na,Ca)(Li,Mg,Al)₃Al₆(BO₃)₃Si₆O₁₈(OH,F)₄.
• Crystal Habit: Indicolite typically forms elongated prismatic crystals, often vertically striated, with a glassy to vitreous luster.
• Colour and Transparency: This specimen shows a vivid blue tone, ranging from deep indigo to lighter hues under light, with excellent clarity in some sections.
• Associated Quartz: Quartz (SiO₂) forms a stable, transparent to translucent crystalline base, enhancing both durability and visual presentation.
• Hardness: Tourmaline measures 7–7.5 on the Mohs scale, Quartz is 7, making this a robust and durable mineral combination.

Indicolite – A Rare Blue Tourmaline

Indicolite is one of the most sought-after members of the Tourmaline family due to its rarity and intense colour. Its name is derived from indicum, meaning indigo blue. Unlike more common green or pink Tourmalines, true blue Indicolite specimens are far less frequently encountered, particularly those displaying vibrant colour saturation and crystal integrity. When naturally associated with Quartz, their rarity and aesthetic value increase significantly.

Collector and Display Value

This specimen not only represents a rare geological occurrence but also offers exceptional display appeal. The interplay of Indicolite’s blue tones with the transparent Quartz matrix creates a striking visual effect. Collectors appreciate these combinations for both their beauty and their scientific significance, as they demonstrate the mineralogical processes that occur in boron-rich, silica-rich environments deep within Earth’s crust.
