This striking specimen features a large calcite etched crystal adorned with okenite and gyrolite crystals, free of matrix. The calcite crystal, measuring prominently across the piece, showcases intricate etching that adds a textured and almost sculptural quality. The okenite appears as soft, cotton-like spheres, their delicate, white fibrous structure providing a striking contrast to the calcite's smooth, reflective surfaces. Accompanying the okenite are gyrolite crystals, which form compact, spherical aggregates with a subtle greenish hue, adding further visual interest to this remarkable specimen. Measuring approximately 17.5 x 5.5 x 6.0 cm, this is an impressive piece both in size and complexity.
Collected from Poona (Pune), Maharashtra, India, in the 1980s, this specimen is a classic example of the region's renowned zeolite-rich deposits. The combination of calcite, okenite, and gyrolite is a hallmark of Indian mineralogy, with Poona being one of the most prolific localities for such aesthetically pleasing and scientifically significant specimens.
The interplay of textures, colors, and mineral species makes this piece an outstanding addition to any mineral collection. Its size and provenance, combined with the iconic minerals of the Deccan Traps, ensure its status as a noteworthy representation of India's mineralogical treasures.
