Ammonite cab ~
Offered here is a large, impressive 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 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 is beautifully gemmy, reminiscent of marmalade jelly, with some drusy pockets and patches on the backside. One of them extends out to the edge, but shouldn't interfere with setting. No doubt it'll make a fascinating piece of jewelry! The cab has a nicely rounded dome of 6mm, a versatile designer shape, and a slick glossy polish both front and back.
Size: 42x33 mm
Weight: approximately 58 carats
Price: $82.00
