A large rock crystal sphere from Madagascar, with luminous thread-like inclusions inside. The fine linear structures appear like frozen light paths within the transparent quartz volume.
Thread-like inclusions can have various mineralogical origins: rutile needles (TiO₂), goethite strands (FeO(OH)), or fine growth streaks along former crystal fronts. Exact identification requires microscopic examination.
Madagascar supplies pegmatite material with particularly clear inclusion structures from the Vakinankaratra region. The high clarity of the surrounding quartz makes it possible to visualize the fine threads in transmitted light.
With a diameter of 26 cm, the sphere is a collector's size for display in showcases. Polished from a clear rough block with defined inclusions, the piece has both gemmological and aesthetic value.
A collector's item with gemmologically valuable internal linear structures.
