A single rock crystal point from Brazil, whose interior is permeated by exceptional ice crystal-like inclusions. The fine microcavities and growth lamellae create the appearance of frozen crystal structures when light passes through them.
Rock crystal is the purest variety of quartz (SiO₂). The inclusion structures classified as frosted inclusions are growth discontinuities that were enclosed within the quartz volume during crystallization. These can be remnants of fluid phases, micro-cavities, or the finest accessory mineral particles.
Such internal structures are didactically valuable: they reveal the growth history of the crystal within its interior. The ice crystal-like appearance is created by the geometric arrangement of the microcavities along the quartz growth axes.
Brazilian deposits in Minas Gerais are globally the most productive source for such clear rock crystal points with defined internal structures.
A collector's item with gemologically valuable internal optics.
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.
