Carletonite (very rare) from Canada (7 grams)

Carletonite is one of the great classics from Mount Saint-Hilaire, which is one of the most species-rich localities in the world. The Poudrette Quarry produces many "best in the world" specimens of a lot of individual minerals including killer Carletonites.

This piece is an attractive thumbnail sized piece showing a good sized, sharp, lustrous, pseudocubic crystal of Carletonite, with very minor matrix on the back.

Keep in mind that most Carletonite crystals are typically measured in mm, and to have a piece over 2 cm, is a big deal.

The color ranges from white on the exterior edges, with that classic indigo hue in the center, for which the species is known. The piece is contacted on both ends, but it still has a few well-formed, shiny crystal faces. 

APPROXIMATE SIZE: 2.2 x 1.6 x 1.3 cm

Carletonite is a very rare mineral that is found only in one location in the world, near the town of Bancroft in Ontario, Canada. It was first discovered in 1945 by a geologist named A. L. Carleton, after whom the mineral is named.

Carletonite is a member of the zeolite group of minerals, which are characterized by their porous structure and ability to absorb and release water molecules. It has a blue to bluish-gray color and is often found in small, needle-like crystals that form in cavities in metamorphic rocks.

Because of its rarity and distinctive blue color, carletonite is highly sought after by mineral collectors and enthusiasts. It is often cut and polished into small decorative pieces that can be used as specimens or incorporated into jewelry designs.

Despite its beauty and scarcity, very little is known about the properties and uses of carletonite. It is believed to have potential industrial applications due to its ability to absorb and filter certain types of gases, but further research is needed to fully understand its properties and potential uses.

Overall, carletonite is a fascinating and rare mineral that is highly valued by collectors and enthusiasts for its unique beauty and rarity.
