No, if you rub or even swipe the silver ring against your face, and there is a black line left on your face, then you are iron deficient.

I have heard hormonal changes and extra acidity in your system can turn your fingers black with real jewelry. I have even heard pregnant people have problems with their rings. LIBYRINTH: One of the most common causes for this is because the gold become oxygenated, causing the iron mixed with gold to surface. If gold in excess of 14 karats causes black or dark green marks on the skin, there is only one reason: an iron deficiency. If a person has an iron deficiency, the hemoglobin in the blood is less able to carry oxygen. Iron is not all that dissimilar from gold, chemically speaking. If a person with an iron deficiency wears gold consistently, a black or dark green mark will form over the area where the gold touches the skin. So take some iron pills and it will help.
I have found that, any time gold turns my skin black/dark green, I am low in iron. I take one iron pill and the black/dark green goes away, until I become low again.
Brown or black marks on fired pottery are usually caused by mineral impurities, usually iron.
Gold is typically a metallic yellow color, while iron oxide can be red, brown, or black.
Iron marks burn the fabric, which damages it, so it may not be removeable. If you can get the black mark off, the fabric underneath it will be weaker than it originally was. To try and remove the stain, scrape off any charring, then pretreat the stain, rinse it, and then wash it as you normally would.
Iron makes leaves green. If trees have green leaves, they have iron.

If you possess gold (or iron pyrite) ore, it should be immediately clear whether gold or iron pyrite is present. You should be able to distinguish which of the two you have. Real gold is rounder while pyrite is more angular and sharp. Gold is relatively softer and more malleable than pyrite. Gold leaves a golden residue instead of a dark green/black residue as left by pyrite. Google images is a good resource for differentiating the visual contrast of the two.
I think you mean fools gold. Fool's gold is made of iron pyrite or FeS2. It is distinguishable from real gold for when you scrape it on paper it leaves a brown line or stain. It is sometimes mistaken for gold because of it's metallic shine.
Both Gold and Iron are metals.
