A large rock crystal sphere from Brazil, with luminous internal inclusions. 21 cm in diameter, a collector's size for showcase display.
Rock crystal is the purest variety of quartz (SiO₂). The inclusions classified as luminescent inclusions are microstructures that appear as bright points or streaks when light passes through them, often fluid inclusions or growth discontinuities.
Brazilian deposits in Minas Gerais are globally the most productive source of clear quartz spheres of collector's size. From a flawless rough block, the entire shape must be created without microfractures, which requires workshop precision.
The internal inclusions tell the growth story of the crystal: each micro-discontinuity marks a crystallization phase, each fluid inclusion a brief change in solution.
A collector's item with educational internal stratigraphy.
Wir beziehen unsere Kristalle direkt aus den Minen, ohne Zwischenhändler. Mehrmals im Jahr sind wir persönlich vor Ort und kennen die Familien, die diese Steine zutage fördern.
Sie erhalten einen fairen Preis für ihre Arbeit. In unseren Minen arbeiten ausschließlich Erwachsene unter sicheren Bedingungen, und davon überzeugen wir uns bei jedem Besuch.
Wie das vor Ort aussieht, zeigen wir in einem Film, der bei uns im Museum läuft.
Robust and suitable for everyday use. Clean with a soft, dry cloth; if necessary, use lukewarm water.
