💫 Hidden-world lore and care
“Geode” describes the structure rather than the mineral. A true geode retains an internal cavity, while a completely filled rounded body may be described more accurately as a nodule, Agate or another locality-specific formation. Labels such as “Quartz geode with Chalcedony rind” reveal more than the word geode alone.
Quartz measures 7 on the Mohs scale, but a geode can still have fragile points, thin edges, fractures, soft matrix or additional minerals. Dust it with a soft brush and support it from beneath. Stable untreated Quartz geodes may be cleaned briefly with mild soapy water, but avoid soaking unknown material, acids, salt, steam and ultrasonic cleaning. Dyed, coated, glued or repaired pieces require especially gentle dry care.
