This is a beautiful combination of Calcite and Stilbite on Apophyllite crystal cluster.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. Stilbite is perhaps the most popular zeolite mineral for collectors. Stilbite is a handsome specimen with its pearly luster and sometimes colorful pink tints. Apophyllite is transparent to translucent and is commonly found in colorless or white varieties, although it can also occur in shades of green, pink, yellow, or brown.
This nice crystal specimen would be a beautiful addition to any new or existing collection.

This is a natural cluster formation of large calcite crystals with hematite inclusions. This piece has some white color to translucent crystals with areas of orange/red coloring from hematite inclusions, with sharp tabular crystal formations. There are some nicks and imperfections on a few crystals but would still shine in the proper setup. They don't take away from how interesting this piece is. Would be a nice addition to any new or existing collection.

Amber golden calcite from Mexico is a beautiful variety of calcite known for its rich golden to honey-colored tones. It often forms in sharp, well-shaped crystals like dogtooth clusters or larger, chunky crystals with smooth faces. These pieces can have a soft glow when light passes through them, making them visually warm and inviting. Much of this material comes from regions like Durango and Chihuahua, areas well known for producing high-quality calcite in many colors.
Amber golden calcite is often associated with confidence, warmth, and personal growth. Some believe it helps boost self-esteem and encourages a positive, motivated outlook, making it a helpful stone during times of change or new beginnings. It's also thought to carry a gentle grounding energy, helping balance emotions while keeping one connected to a sense of inner strength.

This is a stunning specimen of calcite cubes on mordenite druse. The crystals are well defined and look beautiful together.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.
Mordenite was first described in 1864 by Henry How. He named it after the small community of Morden, Nova Scotia, Canada, along the Bay of Fundy, where it was first found. It is one of the most abundant zeolites and is found in volcanic rock such as rhyolite, andesite, and basalt. It is associated with other zeolites such as stilbite and heulandite.
