全部拍賣 / Ethnographic / Hopper Quartz Scepter-Shaped - Height: 18 cm - Width: 112 cm- 2.7 kg
Scepter-Shaped Hopper Quartz with Tourmaline Inclusions A striking partially polished Quartz specimen distinguished by its sculptural scepter-like form, pronounced hopper growth and contrasting Tourmaline inclusions. The crystal displays characteristic stepped and recessed growth patterns, produced when the outer edges of the Quartz developed more rapidly than the central faces. This creates the distinctive geometric “hopper” structure, with layered surfaces and sharply defined natural formations that give the specimen considerable visual depth. Dark Tourmaline inclusions are visible within and across the Quartz, creating fine linear accents and strong contrast against the clear to milky body of the crystal. Together with natural internal fractures and veils, these inclusions make the piece especially interesting when viewed under changing light. The partial polish has been carefully applied to reveal the internal structure while preserving important natural surfaces and growth features. The result is a balanced combination of raw mineral character and refined presentation. Quartz is silicon dioxide (SiO₂), one of the most widespread minerals in the Earth’s crust, while Tourmaline belongs to a complex group of borosilicate minerals commonly occurring as elongated prismatic crystals. With its unusual morphology, architectural form and contrasting inclusions, this specimen works particularly well as a decorative mineral sculpture, collector’s piece or statement object for a contemporary interior or cabinet of curiosities.
