4.8" Apophyllite Crystals after Chabazite with Stilbite - India

This is a 4.8" wide association of clear apophyllite after red chabazite crystals. Interspersed are peach stilbite crystals that provide a nice color break in the specimen. Apophyllite after chabazite is a rather uncommon find in the natural world, making this piece quite a jewel in any collector's cabinet. The specimen was collected in Maharashtra, India.

Comes with an acrylic display stand to assist with presentation.

This specimen comes from the Deccan Traps (a large igneous province and one of the largest volcanic features on earth) in the Pune Province of India. In the course of quarrying for other materials or digging wells sometimes large pockets of zeolites and other minerals are unearthed in the volcanic rock.

Stilbite is probably the most common zeolite found in these deposits. Crystals often form flowery, bowtie or hourglass shaped structures and come in a variety of colors. Some of the most beautiful colorations are the pink or peach tints. Apophyllite while not a zeolite itself is almost always found associated with zeolites in the same pockets. It has two crystal habits, a rectangular prism capped by a steep four sided pyramid or a pseudo-cubic structure. While not a well known mineral to the general public it is popular among mineral collectors due to it's pastel colors and beautiful crystal formations.

Chabazite is the name for a series of minerals that include chabazite-Ca, chabazite-K, chabazite-Mg, chabazite-Na and chabazite-Sr. The variety of the crystal is dependent on the cation present during formation (Ca, K, Mg, Na or Sr). The red chabazite is commonly a calcium dominant variety (chabazite-ca), the most prevalent of the chabazite series. Crystals usually exhibit a rhombohedral habit and can display a variety of colors including red, orange, yellow and colorless.

The general chemical formula of chabazite is (Ca,K2,Na2)2[Al2Si4O12]2 · 12H2O .
