Here are a couple pendants that are made of iron, silver and stone. The iron discs were formed red hot and given a dimpled texture. The silver settings and bails are attached with rivets. I very much like the dual texture and color of the forged iron and polished silver. Iron is very much under appreciated but our bodies know better. Not only does iron make up hemoglobin, but is an important component of many crucial enzymes, hormones, neurotransmitters, and amino acids in our bodies. Iron oxide (yes rust!) is what makes our blood red and carries oxygen to our cells. Its oxidative ability is what allows it to freely exchange oxygen with carbon dioxide which would quickly acidify and poison our system. After the hemoglobin's short 3 month life, our liver breaks down these cells and clings onto every molecule of iron for eventual generation of new blood cells. So is the intelligence of our bodies. Although iron is, by mass, the most common element, our bodies know it is also the most valuable and would not trade it for gold.
