Locality: Tyrol, Austria
Size: 7.4 x 5.1 x 3.2 cm
Formula: Na(AlSi2O6) · H2O
Description: Analcime is a member of the zeolite group and often occurs together with other zeolites. However, it is closely related in structure to the feldspathoid group and is occasionally classified as a feldspathoid, together with a similar mineral Leucite. However, most mineralogical sources, including the IMA, classify Analcime only as zeolite and not as a feldspathoid.
Usually, the crystals form is distinctive, well-shaped trapezohedrons (https://skfb.ly/6UTSv). Crystals are usually equidimensional, though they are occasionally distorted. This crystal has a classic porcelaneous luster, nicely accented with the oxide tinting.
