Tourmaline – The Value of Rarity
The Rubaya mines, located in North Kivu, Democratic Republic of Congo, are known for having produced some of the world’s finest elbaite tourmalines between 2019 and 2021. However, production has drastically declined, making specimens of this quality increasingly difficult to find.
This crystal is even more unique due to its perfectly preserved termination, characterized by an antilogous pole with well-defined trigonal pyramids, a hallmark of excellence in tourmaline crystallization. The combination of structure and golden coloration makes this a reference piece for expert collectors.

Tourmaline – The Secret Behind Its Color
🌞 The vibrant yellow-green color of this tourmaline is a geological mystery still being studied. It is believed to result from the combination of iron, manganese, and titanium, with trace amounts of these chromophore elements interacting in ways not yet fully understood.
⚗️ Tourmalines are among the most chemically complex minerals, with a borosilicate composition that allows for a vast range of chemical substitutions, leading to an infinite variety of colors and shades. This makes each specimen unique: no two tourmalines are ever exactly alike.

Tourmaline – A Natural Work of Art
Nature is the greatest sculptor, and this specimen proves it. Unlike the typical single-crystal formations of Rubaya, this tourmaline consists of multiple intergrown prisms, creating a natural sculpture with a powerful visual impact. Each crystal, with its varying heights and thicknesses, contributes to a perfect balance of form and structure.
Tourmalines from this locality are famous for their exceptional transparency, sharp terminations, and high luster, but an architectural configuration of this complexity is extremely rare. Observing this specimen under light, one is mesmerized by the interplay of reflections across its crystalline surfaces.

Tourmaline – The Collector’s Jewel
Tourmaline from Rubaya is highly sought after by collectors, not only for its striking polychromy but also for the exceptional rarity of its structural features.
💎 This specimen is particularly unique, showcasing two distinct crystals of the same mineral species—elbaite—where one is terminated by the antilogous pole and the other by the analogous pole. Such a formation is seldom encountered and adds to the specimen’s desirability among elite collectors and this specimen is a true rarity.
Not only does it feature extraordinary color zoning, but it also displays a unique interplay of transparency and luster, with its polished surfaces reflecting light like a prism.
Its growth history is written in its striation patterns, natural markings that reveal the crystal’s slow formation within pegmatitic cavities. These striations act like fingerprints, telling the story of the forces that shaped this mineral into the spectacular gem we see today.

Fluorite [CaF₂] – A Delicate Alpine Jewel in Soft Violet
⛰️ From the majestic Italian Alps comes a rare fluorite specimen, distinguished by its delicate light violet hue, a shade reminiscent of lavender fields at sunset. This crystal captivates with its remarkable transparency and perfectly lustrous faces, which reflect light in a mesmerizing display of brilliance.
Fluorite, with its chemical formula CaF₂, is known for its wide range of colors, but light violet variations are particularly prized for their rarity and beauty. These gems form through hydrothermal processes, where fluoride-rich solutions seep into fractures of Alpine rocks, crystallizing over time into these natural wonders.
👉 This specimen is not for sale, but enthusiasts and collectors will have the exclusive opportunity to admire it in person at the Bologna Mineral Show, taking place from March 14th to 16th at the UNIPOL Arena in Bologna. A unique occasion to witness up close the elegance and distinctiveness of this Alpine treasure!
