Collection: Mordenite Specimens

Mordenite is a zeolite mineral that often forms delicate fibrous or hair-like crystal masses, frequently found alongside other zeolite minerals such as stilbite. Its fine, radiating crystal habit and the contrast it creates against companion minerals make it a distinctive addition for mineral collectors interested in zeolite groups and secondary mineral formations found lining cavities in volcanic rock.

This collection features red mordenite specimens, many paired with stilbite, ranging from smaller pieces around 112g up to larger specimens exceeding 1,900g. There are also standalone red mordenite specimens without stilbite for those wanting to focus on the mordenite crystal structure alone. Buyers should look closely at the crystal formation, the coloration of the mordenite, and how the stilbite (where present) is distributed across the specimen, as well as choosing a size that suits their display space.
