A Celestine Chrysanthemum Stone from Guilin, China: white radial celestine crystal aggregates on a dark carbonate matrix, whose growth geometry resembles chrysanthemum blossoms. A rare mineralization variant.
Celestine (strontium sulfate, SrSO₄) crystallizes orthorhombically in tabular or prismatic habits. The radially radiating aggregates visible here are formed by growth from a central crystallization nucleus in all directions, a phenomenon classified as spherulitic.
The dark matrix is sediment-organic colored limestone. The strong light-dark contrasts between white celestine rays and the black carbonate background make the piece a very legible teaching object of sediment mineralization.
Such chrysanthemum stones are formed by diagenesis processes, in which strontium-rich solutions in sediment cavities formed the radial celestine aggregates. Guilin is one of the few deposits worldwide that supplies such material in collector quality.
A collector's item with crystallographic educational value and visually strong contrast.
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.
Very sensitive to sunlight, may fade. Store in the shade, never immerse in water, clean only with a soft, dry brush.
