Entirely hand fabricated from .999 pure silver. No solder was use for closing the links but rather they were individually fused closed therefore even more solid then soldering. The Eye and links are engraved by hand using a sharpened nail.
It features a 11mm genuine fossilized Lepidodus tooth also known as a Toadstone during the Medieval period. Lepidotus is an extinct fish from the late Jurassic period approximately 150 million years ago so YES this is very old!
No casting and no electric tools were used throughout the entire fabrication.
