This is an exceptionally large specimen of a classic “bowtie” Stilbite, nearly 5” (12.5 cm) wide! It is perfect, and I don’t say that often. It has just a small bit of Heulandite matrix attached to the bottom to give it balance and contrast. One...

This is not your typical Apophyllite and Stilbite piece out of India - the Apophyllite crystals are clear, gemmy and perfectly terminated and the Stilbite crystals are a light salmon color with a pearl luster. The overall piece is so lustrous it looks wet!...

I know Zeolites can be a yawner, but every once in a while you come across an eye-catcher, and I consider this piece to be just that. It features a large aggregate of numerous “bowtie” shaped, translucent and lustrous pink/salmon colored Stilbite crystals. The...

A rare and beautiful specimen featuring a cluster of deep-green, radiating Heulandite crystals with a small matrix of Stilbite and Apophyllite attached. The Heulandite crystals are well formed and exhibit a flower-like radial formation. A rare and very collectable color for this otherwise common...

This is a very large, unusual and rare plate of intergrown Mordenite balls. I simply haven’t seen anything quite like it. Mordenite is considered one of the rarer Zeolites, yet there’s still plenty around - but a plate like this - not so much....

A beautiful and delicate spray of acicular, transparent, colorless to white Scolecite crystals on a base of dense Scolecite crystals. The contrasting direction of the upper cluster of crystals to the base is really eye-catching. A very aesthetic piece in great condition, especially given...
