Unique aesthetic Heulandite snail-like shaped3D ModelNoAI
Locality: Faroe Islands, part of the Kingdom of Denmark
No.: 6071
Size: 7.5 cm x 4 cm x 3 cm
Formula: (Ca,Na)5(Si27Al9)O72 · 26H2O
Description: This is a unique aesthetic pearlescent cluster of Heulandite crystals on a thin and fine-grained volcanic matrix (?basalt). The shape of this specimen, snail-like, is unique!
Heulandite is one of the most common zeolite minerals. It has a very distinctive crystal form and has a noticeable pearly luster on cleavage surfaces. Almost all Heulandite specimens in collections are Heulandite-Ca. A distinction among the different Heulandite types is rarely made, and the members are generally just termed Heulandite without further breakdown. Heulandite is named after English mineral dealer Henry Heuland (1778-1856), who would frequent trips to Iceland collecting Heulandite and other zeolites.
