An amethyst geode pair from Uruguay, in whose violet interior lining small white calcite crystals have grown as a second generation of minerals. An unusual combination in which two minerals have sequentially formed the same geode.

An amethyst geode pair from Uruguay, in whose violet interior lining small white calcite crystals have grown as a second generation of minerals. An unusual combination in which two minerals have sequentially formed the same geode.
Amethyst crystallized in the original lava geode from silica-rich solutions over millions of years. After this growth process ended, calcium carbonate-containing solutions penetrated the remaining cavity and deposited the calcite scalenohedra over the amethyst tips.
Such multi-generational geodes are didactically valuable: they document that a single cavity structure has accommodated various solution chemistries over long geological periods. The changes between quartz and carbonate solutions typically follow tectonic activity phases.
Uruguayan material from the Artigas Basin is among the most intense amethyst sources worldwide. The combination with calcite crusting increases its collector's value because it incorporates geology as a visible layered narrative.
A collector's item with multi-generational genesis and visually contrasting tension.
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.
Protect from direct sunlight, may fade over time. Acid-sensitive calcite matrix, no vinegar or acid cleaners. Clean with a soft, dry cloth.
