Ammonite cab ~
Offered here is an intriguing 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, about the color of marmalade jam, and shows a fascinating suture pattern of growth events which can be seen as white lines. The shape of the lines almost perfectly echoes the outline of oak leaves. Those interlocking sutures are thought to have allowed the living ammonite to withstand the immense pressure of the underwater depths. Very translucent when backlit. No doubt it'll make a fascinating piece of jewelry! The cab has a rounded dome of 5+mm, a designer 'catseye' shape, and a slick glossy polish both front and back.
