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 golden amber and olive colored cab has a strong suture pattern of growth events which can be seen as white lines, roughly resembling 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 example has areas of translucence, reminiscent of marmalade jelly, while the olive green areas are opaque. The cab has a nicely rounded dome of 5.5mm, a designer 'pillow' shape, and a slick glossy polish both front and back.
Size: 30x26mm
Weight: approximately 45 carats
