A mostly loose double terminated grouping of colorless to slightly pinkish stilbite crystals. Lustrous and in good condition all around with minimal attached matrix on the edge of the bottom. The specimen comes with a previous label from the collection of Ray DeMark, plus a second label from Michigan Technological University, Seaman Mineral Museum. From the early 1990s. Located in the remote Siberian region within the Nizhnyaya Tunguska River basin of Krasnoyarsk Krai, Russia, the Amudikha River area features extensive basaltic rock formations. These volcanic layers contain cavities created by ancient hydrothermal activity, which host an exceptional suite of secondary minerals. Among them, attractive crystals of stilbite occur alongside other zeolites within the altered basalt. Due to the extremely rugged and isolated terrain, systematic commercial mining has not taken place, but collecting is carried out occasionally by specialized mineral expeditions and regional field researchers who recover fine specimen material from these remote outcrops.
