This is a beautiful combination of Apophyllite, Stilbite and Calcite on Chalcedony Druse. It is a large specimen at over 2 kg and has many double terminated crystals.
Stilbite is a zeolite mineral appreciated for its delicate crystal formations and pastel hues, ranging from colorless to white, yellow, pink, and peach. It forms distinctive tabular crystals with a bowtie or butterfly shape and exhibits a vitreous to pearly luster.
One of the distinguishing features of apophyllite is its ability to form well-defined crystals with a pyramid-like shape. These crystals often exhibit a prismatic or pseudo-cubic habit and have a vitreous luster. 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.
Chalcedony is a microcrystalline Quartz found in many different colours and patterns. It has a number of crystals grouped under it many of which are very familiar, including Agate, Carnelian, Chrysoprase, Aventurine, Jasper and Onyx.
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. This huge crystal specimen would be a beautiful addition to any new or existing collection.
