Ammonite cab ~
Offered here is a 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 dark olive green, and shows an intricate 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. A tiny pinpoint void or two are the only flaws I can find, easily overlooked. No doubt it'll make a fascinating piece of jewelry! The cab has a well rounded dome of 5+mm, and a slick glossy polish both front and back.
