Ammonite cab ~
Offered here is a splendid 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 has shades of amber and olive green, with a fascinating suture pattern of growth events which can be seen as white lines. Some of them 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. When backlit, the stone shows a lovely warm translucence that reminds me of marmalade jam. No doubt it'll make a fascinating piece of jewelry! The cab has a well rounded dome of 6mm, a versatile shape, and a slick glossy polish both front and back.
