Detailed Description

This specimen features natrolite crystals in clusters – the left-hand cluster is a beautiful intergrown group of crystals and crystal sprays. The natrolites are sharp with good lustre and glassy lustrous terminations. Under short-wave ultraviolet light, the natrolite crystals are green and the crystals in the left-hand cluster has very bright green terminations. The natrolite crystals on this one occur together with minor microcline (fluoresces red) and brecciated aegirine. In excellent condition – a couple of contacted natrolite crystals at the right. Stands perfectly as photographed – a beautiful display piece.

About these Natrolites

Mont Saint-Hilaire is one of the world’s most famous and most important mineral localities, with over 430 mineral species. Many are micros and some are occasionally found as display specimens. MSH has produced nice natrolites periodically over the past few decades – the natrolites from this pocket are particularly elegant, with excellent crystals. In addition, they fluoresce a beautiful bright green under short-wave ultraviolet light.

For a long period dating back over 10 years, MSH was completely closed to collecting, and although it remains closed to general collecting (with only limited controlled access), happily, the company is actively coordinating to allow the preservation of specimens once again. These natrolite specimens are from one such recent collecting effort to preserve specimens from this amazing place. This lot was acquired together with David K. Joyce.
