Goosecreekite (excellent large rare specimen)

Item Description

Certainly the finest examples of the very rare zeolite species Goosecreekite come from India. They are unmistakably better than any Goosecreekite specimens from other world localities by many orders of magnitude. Were it not for these specimens, most people wouldn't even have much of a reference for Goosecreekite as a species. The mineral gets its name from the New Goose Creek Quarry in Leesburg, Virginia, USA. Despite the fact that the very best Goosecreekites come from India, they still do not get the attention they deserve for their size and quality. These are simply the largest and most impressive crystallized Goosecreekites extant. This specimen features a 4.7 cm group comprising excellent quality, lustrous, snow white bladed crystal Goosecreekite forming a semi-radial "burst", sitting on sparkling white Quartz crystals on basalt matrix. There is another smaller secondary group of Goosecreekite underneath the larger group for reference. No damage, and an absolutely top-notch display quality specimen of what is a very rare mineral species. These are rare on the market now, the best pieces came out 20+ years ago. Valued $4,000-$5,000. From the collection of Vasco Trancoso, a medical doctor and prominent mineral collector from near Lisbon, Portugal (https://www.mindat.org/user-11954.html). He assembled his mineral collection over the course of 60 years, and built a fine worldwide display collection that we recently purchased.
