Stilbite-Ca with Chalcedony

Item Description

This is a wonderful representative example of an old-time Stilbite-Ca from circa 1970s-1980s from the Mumbai area in India. Keep in mind that when Indian Zeolites and associated minerals first appeared on the market, they were some of, if not the most significant examples of their respective species ever found. The size, quality, color, associations and presentations of the pieces were unmatched then and still are today. They might be common on the market now, but these Stilbites are as good as they get on a worldwide scale. This piece hosts sharp, lustrous, well-formed, light peach colored Stilbite-Ca crystals measuring up to 4.1 cm on drusy white Chalcedony matrix. The main crystal is doubly-terminated and undamaged. A beautiful example of this classic material.
From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008) with an old label from "BURMINCO". Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974 ( https://www.mindat.org/photo-326405.html ).
