Aragonite on Quartz with Fluorite Inclusion – China
This exquisite mineral specimen features sharp, caramel-brown aragonite crystals beautifully perched on a bed of white quartz. Sourced from China, the piece offers an outstanding example of orthorhombic crystal growth. Each aragonite formation radiates outward in a starburst-like structure, creating a dramatic and highly sculptural aesthetic. The natural geometry and balance make this an ideal showpiece for advanced collectors.
The quartz base provides both contrast and stability. It highlights the complexity of the aragonite clusters while enhancing the overall visual texture of the specimen. On the underside, a fluorite inclusion—though not immediately visible—adds extra mineralogical interest. Under good lighting or when examined in hand, this subtle violet to greenish hue from the fluorite adds depth and variation.
Aragonite is a calcium carbonate mineral (CaCO₃) and one of the three main polymorphs of this chemical composition, along with calcite and vaterite. It forms under high-pressure or low-temperature conditions, commonly in hydrothermal veins, hot springs, and marine environments. While aragonite is relatively stable in its natural setting, it slowly transforms into calcite over time when exposed to surface conditions. This transformation makes high-quality aragonite specimens increasingly rare and desirable.
The quartz matrix (SiO₂) is durable and widely found, yet in this piece, it plays a key supporting role. Its crystalline texture adds contrast to the aragonite while anchoring the specimen securely. The fluorite (CaF₂) inclusion further elevates the specimen’s scientific and collector value, especially considering the rarity of this trio forming together in a single matrix.
This piece is ideal for collectors who value crystallographic precision, mineral associations, and locality-based character. It reflects both geological beauty and structural complexity—perfect for display or academic interest. This is not only a fine aesthetic piece but also a scientifically meaningful addition to any serious mineral collection
