This exceptional mineral specimen showcases rare pentagonite crystals elegantly perched on a matrix of crystalline heulandite, creating a refined and highly collectible zeolite association. The sharp geometry of the pentagonite crystals contrasts beautifully with the sparkling, glassy heulandite, resulting in a specimen that is both visually striking and mineralogically unique.
This piece offers a harmonious balance of rarity, aesthetic sophistication, and scientific significance—ideal for the advanced collector or curated mineral collection.

Pentagonite is a hydrated calcium vanadium silicate known for its distinctive five-sided prismatic crystal habit, a morphology shared by very few minerals worldwide. It commonly occurs within select zeolite environments, making quality associations particularly desirable.
The accompanying crystalline heulandite, a member of the zeolite group, exhibits well-formed crystal faces and vitreous luster, serving as both a complementary visual backdrop and an important indicator of the geological conditions that allowed pentagonite to form.
Pentagonite is regarded as one of the rarest zeolite-associated minerals, with specimens from productive localities becoming increasingly scarce. Examples featuring well-defined pentagonite crystals on fully crystallized heulandite are notably uncommon, as many specimens are found on less aesthetic or massive matrix. The clean presentation and strong contrast in this piece place it well above average for the species.
Rare pentagonite with distinct prismatic crystal form
Sparkling crystalline heulandite matrix with excellent luster
Strong visual contrast between primary mineral and matrix
Sought-after zeolite association with limited availability
Suitable for advanced collectors or curated displays
Pentagonite continues to demonstrate steady collector demand due to its rarity, limited availability, and unmistakable crystal habit. Specimens that pair sharp pentagonite crystals with premium matrix minerals—such as crystalline heulandite—represent a higher tier within the market. As availability diminishes and collector desire grows, well-composed examples like this are increasingly viewed as stable long-term holdings within serious mineral collections.
