Description
~ Ammonite cab ~

Offered here is a large 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 and yellow, with a small patch of olive green, and shows a fascinating suture pattern of growth events which can be seen as white lines. Some 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. This one shows a gemmy translucence that looks like marmalade jam when backlit, with a little sparkly crystalline cavity, and two more larger vugs on the backside. No doubt it'll make a fascinating piece of jewelry! The cab has a well rounded dome of 6.5mm, and a slick glossy polish both front and back.

Size: 50x21 mm
Weight: approximately 45 carats
