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 rich amber colored cab shows an interesting suture pattern of growth events which can be seen as white lines, including some that roughly 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. Despite being a somewhat darker example, this one's very gemmy and translucent, with a few tiny pinpoint voids being the only flaws I can find. No doubt it'll make a fascinating piece of jewelry! The cab has a low rounded dome of 5mm, and a slick glossy polish both front and back.
