Stilbite is a zeolite mineral that forms flat, tabular crystals and bow-tie shaped clusters, usually in the cavities of basalt, often alongside apophyllite. It is soft (3.5 to 4 on the Mohs scale), glassy to pearly, and found in white, peach, pink and brown. Collectors and crystal shoppers also know it as a gentle, loving stone in modern crystal lore.

The Physical Properties of Stilbite

Stilbite belongs to the zeolite family, and is found in zeolite deposits all around the globe. Its crystal structure is all flattened and tabular with pointed terminations. And it can even form in these really interesting clusters! There's also a special kind of Stilbite that collectors go wild for. These crystals are big and have this unique bow tie shape.

When it comes to where it's found, Stilbite is typically found with Apophyllite and Heulandite, in basalt and other volcanic rocks. Stilbite usually keeps it cool with a colourless or white vibe, but it can also go all out with brown, beige, yellow, pink, red, orange, or grey shades.

Stilbite is a bit of a softie with a hardness rating of 3.5 to 4. It's delicate and rocks a glassy, pearly, or dull shine. In terms of transparency, it can either be totally see-through or a little translucent, letting light peak through just a little bit.

The Metaphysical Properties of Stilbite

In crystal lore, Stilbite is called a stone of love, linked with the heart chakra and with joy, peace and acceptance. It is a popular pick for couples and for anyone who likes a soft, uplifting piece on a shelf or altar. You can find it in our Stilbite specimens.

Stilbite is also a favourite in manifestation practice. In crystal lore it stands for letting go of limiting beliefs and for encouragement toward your dreams, goals and ambitions.

It also turns up in dream work. Practitioners keep it near their journal and say it is a stone of mental clarity that helps with remembering dream details when you wake up.

At bedtime, some people place Stilbite on a nightstand or under a pillow as part of a calm, quiet evening ritual. It is a symbol and a habit-setter, nothing more.

The Lore of Stilbite

Older crystal books describe Stilbite as a cleansing stone, a symbol of purity and clarity. These are folk traditions and symbolism only, and they do not describe anything the mineral does.

Writers have also linked Stilbite with the voice and the throat chakra, as a stone for speaking up with kindness. Again, this is symbolism, not science.

The History of Stilbite

The name Stilbite comes from Greek culture. It comes from the word stilbein, which means to glitter, and that name is spot-on! Stilbite' has these cleavage surfaces that shimmer and shine like nothing else.

J.C. Delametherie stumbled upon Stilbite in 1797. But it wasn't until 1801 when R.J. Hauy gave it the official name we know today. Initially, Stilbite was considered a single mineral species, but in 1997, the zeolite subcommittee of the International Mineralogical Association (IMA) decided to split it into two subcategories: Stilbite-Ca, which is a calcium-rich type, and Stilbite-Na, which is a sodium-rich type.

Fun fact: Stilbite-Ca is more common than Stilbite-Na, so when collectors talk about Stilbite, they're usually referring to the calcium-rich kind. Stilbite of both kinds can be found in some pretty cool places around the world, such as Canada, Iceland, India, Italy, Scotland, and the USA.

Something I found through learning about Stilbite crystals that I thought was pretty interesting, is that throughout history, Stilbite has been put to work in all sorts of everyday things. It's been used in water and gas filters, laundry detergents, and even fertilisers. Not only is this crystal gorgeous and sought after in the crystal world, it also has a practical side.
