Detailed Description

A pair of beautiful zircon crystals features in the middle of this piece. These crystals are dark red, sharp with great form, have super modification faces and high lustre. They are translucent and have very nice internal play of light. The crystal at the right has lighter-coloured areas as well. In excellent condition, no damage. Sits perfectly for display as photographed. The zircon crystals fluoresce yellow under short-wave ultraviolet light, as shown in the last photo. This is great zircon specimen.

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.
