Specimen # 101986
Mineral: Zircon
Location: Zircon, Astor Valley, Gilgit-Baltistan, Pakistan
Size: 4.5 x 4.1 x 2.9 cm


Detailed Description

This piece features a beautiful pair of very sharp red zircon pyramids at the top, centre. The one on the left is just the top termination poking out, with deep red colour. The one on the right is also sharp and glassy as it faces forward – this crystal is more exposed and is more rounded at the other termination (this latter termination isn’t actually visible from the main display angle, as I’d display it. In excellent condition – no damage. The zircon crystals fluoresce yellow under shot-wave ultraviolet light, as shown in the last photograph. Sits perfectly for display as photographed. These two zircon terminations are so well-defined and lustrous – they look like little jewels.

About these Zircon Specimens

These zircons are from a relatively large new find of zircons from Astor Valley, in Pakistan. A locality that has sporadically produced moderate amounts of material in recent years, this recent find produced a large number of pieces. However, fine zircons are proportionally very few. There are two key reasons for this. First, the zircons are enclosed within solid rock with other hard constituent minerals, such that a good number of zircons were broken when they were collected. However, the second reason is the much more prevalent issue based on the material I’ve seen: the zircon crystals seem to have formed more or less contemporaneously with most of the other minerals in the deposit – feldspar, biotite mica, and pyroxene – and as a result, most of the zircon crystals are not fully developed. Instead, most zircon crystal growth was interrupted by the growth of these other minerals, and therefore most zircons are simply incomplete, or malformed. And yet, among well over 1000 pieces I went through from this find, there were a few excellent specimens.
