Apophyllite is a mineral known for its distinctive crystal formations, often occurring in clusters with a unique beauty.  Its crystals are usually colorless or white, allowing them to be transparent or translucent. Although, some specimens may exhibit a greenish, yellowish, or pinkish tint due to the presence of impurities.

Prehnite can form prismatic, tabular, or pyramidal crystals, but usually occurs in botryoidal, reniform, stalactitic, granular, or compact habits.  It is usually green in colour, but may be white, colourless, yellow, or gray.  It has a colourless streak.  Prehnite is transparent to translucent, with a vitreous to pearly luster.  Prehnite forms in cavities in basaltic lavas.

Apophyllite is believed to promote self-reflection and authentic self-expression, helping to reduce stress, release mental blockages, and overcome anxiety by revealing truth and facilitating the release of suppressed emotions. Prehnite is considered a stone of unconditional love, known for its healing properties, especially for healers, and is thought to bring harmony to spaces, assist in decluttering, and create a healing sanctuary, particularly when used in gardens.

Okenite is a silicate mineral that is usually associated with zeolites. It most commonly is found as small white "cotton ball" formations within basalt geodes. These formations are clusters of straight, radiating, fibrous crystals that are both bendable and fragile.

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.

Quartz crystals are among the most abundant and well-known minerals on Earth. It belongs to the hexagonal crystal system, and typically forms six-sided prismatic crystals with a pointed termination. Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent. 

Prehnite can form prismatic, tabular, or pyramidal crystals, but usually occurs in botryoidal, reniform, stalactitic, granular, or compact habits.  It is usually green in colour, but may be white, colourless, yellow, or gray.  It has a colourless streak.  Prehnite is transparent to translucent, with a vitreous to pearly luster.  Prehnite forms in cavities in basaltic lavas.
