Silvialite
Silvialite is a rare calcium aluminum silicate sulfate mineral with the chemical formula Ca4Al6Si6O24(SO4). It belongs to the tectosilicate class in the Strunz classification system (9.FB.15) and crystallizes in the hexagonal crystal system. The mineral typically exhibits a vitreous luster and is colorless to white in appearance. It has a relatively low hardness on the Mohs scale and a moderate density. Silvialite is notable for its sulfate content, which is uncommon in tectosilicates, and is considered a member of the feldspar group due to its structural and compositional similarities.

Overview
Silvialite is a rare calcium aluminum silicate sulfate mineral with the chemical formula Ca4Al6Si6O24(SO4). It belongs to the tectosilicate class in the Strunz classification system (9.FB.15) and crystallizes in the hexagonal crystal system. The mineral typically exhibits a vitreous luster and is colorless to white in appearance. It has a relatively low hardness on the Mohs scale and a moderate density.

Etymology
Silvialite is named after Silvia Hillebrand, in recognition of her contributions to mineralogy.
How to recognize it
Silvialite can be identified by its hexagonal crystal habit, vitreous luster, and colorless to white color. It has a moderate hardness on the Mohs scale, though the exact value is not specified. A streak test may help distinguish it from other tectosilicates, and its sulfate content can be a key differentiator. It is often confused with other calcium-rich silicates due to similar physical properties.
Trivia
Silvialite is notable for its rare sulfate content within the tectosilicate class, making it chemically unique. It is named after a person rather than a place, which is uncommon for mineral nomenclature. Its hexagonal crystal system is also a distinguishing feature among tectosilicates, which more commonly form in other systems.
Indicative prices
Silvialite is a rare mineral and typically not available in commercial gem or jewelry markets. As a collector's specimen, its price is indicative and varies by source, with high-quality, well-formed crystals potentially commanding hundreds to thousands of euros. The value depends on origin, clarity, and aesthetic appeal, but it is not commonly traded as a gemstone.
