This bead is made from whole fossil ammonite from Madagascar.  It has been carefully prepared to reveal some gem shimmering, iridescent gemmy fossil shell on parts of the surfaces. The bead has a 2mm side drill hole, measurements are shown in the title. 

CHAIN NOT INCLUDED.  I have a variety of chains for sale in my store in different styles and lengths.  Most, but not all, chains will fit most of my beads.  If you want a specific chain for a specific bead check first.  Feel free to check out all the items here in my DVHdesigns Store and don't hesitate to contact me with general inquiries or about custom work that I could make and list for you.  Thanks for shopping DVHdesigns!   

Here is some information from Wikipedia about ammonites which...

"an extinct group of marine invertebrate animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs are more closely related to living coleoids (i.e. octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species. The earliest ammonites appear during the Devonian, and the last species died out during the Cretaceous–Paleogene extinction event.

Ammonites are excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geological time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled and nonspiraled forms (known as heteromorphs).

The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder (d. 79 AD near Pompeii) called fossils of these animals ammonis cornua ("horns of Ammon") because the Egyptian god Ammon (Amun) was typically depicted wearing ram's horns.[1] Often the name of an ammonite genus ends in -ceras, which is Greek (???a?) for "horn"."

Here is some metaphysical information on ammolite I found online from Universallifetools web site...

"Ammolite is one of the key crystals on Earth today that we can work with in order to be conscious and active leaders of this evolutionary shift. Ammolite assists us in anchoring our energy field into the electromagnetic field of mother Earth, and into her crystalline core to assist us in fully awakening our DNA. As our ‘junk DNA’ becomes active, we have the potential to grow as a human species in LOVE, consciously Living the One Vibrational Energy that gives rise to all of creation. As we grow in LOVE we honour our diversity, and come together in unity and enduring peace.

Traditionally, Ammolite is placed over the Light Activation Point (the energy centre just above the third-eye) or worn as a pendant over the higher-heart, to support its greatest potential of weaving the threads of awakened wisdom through every level of being. Within our holographic universe each of us are fractals of the whole, thus as we individually embrace our highest potential, we are the highest frequencies of light, love and illumination for all of creation to do the same."
