Ammonite cab ~
Offered here is a large deluxe cabochon cut from a fossil ammonite, from Madagascar. The species is Cleoniceras madagascariense, and I'm told it lived hundreds of millions of years ago. This example is golden amber with some opaque olive green. It exhibitss a fascinating suture pattern of growth events which can be seen as white lines, many of which resemble the shape of oak leaves. Those interlocking sutures are thought to have allowed the living ammonite to withstand the immense pressure of the underwater depths. This one's particularly attractive to my eye, with very gemmy, translucent areas that look like marmalade jam when backlit. The backside has a crystalline pocket, completely lined with drusy crystals. No doubt this one'll make a fascinating piece of jewelry! The cab has a high and well rounded dome of 6mm, and a slick glossy polish both front and back.
