Polished Hematite Freeform A polished hematite freeform with a deep charcoal-black appearance and a smooth, reflective finish. Its broad face, gently tapered top and rounded edges give the piece a clean sculptural silhouette, while fine tonal variations add interest to the dark surface. This understated stone accent works well on a desk, shelf or console, where its dark palette can anchor a display of lighter minerals, wood or metal. The freeform shape offers a softer alternative to a geometric carving while retaining a clear, balanced presence. Approximate dimensions: 13.6 × 9.5 × 4.7 cm. Weight: 1115 g. Hematite is iron oxide, Fe₂O₃, and an important iron ore. A curious feature is that even dark, metallic-looking hematite typically produces a reddish-brown streak when tested on unglazed porcelain—an indication of the red pigment hidden within its darker appearance.
