A gorgeous deep red zircon crystal – sharp, very lustrous, with nice internal red sparkle under the lights. The crystal measures 1.4 cm. In excellent condition – there is chipping at the back corner of the termination, but it faces back and does not stand out at all as displayed. Stands perfectly for display as photographed, and I would angle it as in the first photo, as that catches the overhead light the best. Fluoresces yellow under short-wave light as shown in the last photo. This is a beauty.
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.
