Ammonite cab ~
Offered here is a large deluxe 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 splendid cab has a 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, with warm amber shades reminiscent of marmalade jelly, as illustrated by the backlit photo. No doubt it'll make an intriguing item of jewelry! The cab has a well rounded dome of 7mm, a designer 'keystone' shape, and a slick glossy polish both front and back.
