Weight (Specific Gravity): Relatively Low – ~2.24 – 2.29. Due to its zeolite structure (with open cavities holding water molecules), it feels notably light for a mineral.
Treatment: Analcime is not treated. Its value is in well-formed, natural crystals for mineral collections. It is not enhanced or synthesized for the gem or jewelry market.
Body (Clarity/Transparency): Analcime is typically transparent to translucent. The finest crystals are water-clear. It has a vitreous luster and is very brittle with an uneven fracture. While it can be colorless, white, or pale pink/green, its perfect crystal form is more valued than its color. It has poor cleavage, but its fragility and sensitivity to pressure make faceting extremely rare and impractical.
