It is known that gold and silver are very plastic and soft metals. Order jewelry from them did not break and did not bend, the jewelry the alloy added to other alloys. For example, copper, which has the ability to darken and oxidize. The more copper contained in the alloy of your jewelry, the faster it will turn black finger under the ring.
Do not forget about the properties of copper to oxidize when interacting with then. Excessive sweating can occur from heat, stress or failure in the endocrine system. If the black under your rings began to appear regularly and thus you feel some unwell are advised to seek the advice of a doctor.
Slightly different is the case with ornaments made of white gold. As a rule, the Committee added the palladium, which theoretically should not cause darkening of the skin under the decoration. Often, however, for cost reduction of alloy, it also adds a Nickel. And this metal can not only cause blackening of the skin, but can cause allergic reactions.
There is a perception that the blackening of the fingers beneath the silver rings indicate any problem in the kidneys and liver. However, scientific evidence to support this version, to date, does not exist.
There is also a "popular" version of the black bars under the rings of precious metals. It is believed that the silver blackens from the fact that accumulates negative energy, and the appearance of black marks under the Golden ring indicates "the evil eye".
Advice 2: Why finger turns black from gold ring
Sometimes gold rings begin to darken and leave a mark on the skin as a result of chemical reactions. Often this indicates the quality of gold, but sometimes can be other reasons.
Most likely, darken not the finger, and the ring. Most often, the darkening gold of the product and the skin under it is called a chemical reaction. The surface of the ring interacts with the substances that are released by the skin in the process of life. Pure gold 999 (24 carat) is a noble metal. It's not dark, because it is not oxidized. Gold 14 and 18 carat are also quite resistant to this process. The darkening of the ring is facilitated by the presence of gold additives – additives, for example, copper. Oxidation processes are more characteristic of gold and 333 of 416 samples (10 carats and below).
If the ring is constantly covered with a dark patina, then with high probability we can say that in gold a lot of additives, and most likely it base. In addition, the ring can quickly get dirty from makeup, perfume, secretions of the sebaceous glands.
Trouble of this kind can provoke and smog. The soot, smoke, exhaust gases interact with gold can cause a darkening of the ring, and then the skin of the finger. Gold holds the pure energy of the sun, he was sickened by the evil and dirt of every kind. By the way, you can not wear it all.
If your gold ring has darkened all of a sudden, it is possible that this is due to the internal state of the organism. One of the properties of gold and to warn of danger and indicate the presence of harmful substances. However, science is right is pointing to that. Ring most often indicates problems with the liver and heart.

If your ring constantly dims then it is often clean. The easiest way is cleaning with tooth powder. Besides gold products recommend brushing with a mixture of water and ammonia. Dropping the ring in the solution for a few minutes, you can easily clean it from dirt.
Advice 3: Why the cross is black
Pectoral cross is made of different metal alloys. Of course, wearing a cross may become dark, to darken and even turn black for a number of different reasons. Superstitious people can make the darkening of the cross for the warning again. In fact, everything is due to the banal reason of not having to mysticism irrelevant.
You will need
- Crucifix, water, liquid dishwashing, ammonia, tooth powder, soda.
Blacken, as a rule, copper, brass and bronze crosses, and silverware (especially the alloy with copper) or gold low sample. This happens because of a chemical reaction of sweat, sebum as well as moisture and oxygen contained in the air, with the metal of that cross.
People who are inclined to a mystical view of things, suspicion and fears, I can say that darkening a crucifix – a sure sign of impending disaster. For example, it is believed that the owner of the darkened cross will certainly get in a bad life situation, get ill or die. Oddly enough, their fears are not without certain grounds. For violations of exchange of substances in the sebum may increase the sulphur content. Sulfur reacts with silver and copper comprising the alloy from which cast the Church's crosses, and decoration darkens considerably. However, not only the body of the sick person secretes increased amounts of sulfur. This occurs, for example, when hormonal changes caused by pregnancy. A lot of sulfur contained in the organisms of people who prefer to eat legumes, eggs and fish.
A perfectly healthy man, whose body is not saturated in sulfur, too, can discover his cross went dark. It's enough to live in areas with a humid climate, especially on the coast. But if near the home of the owner of the Church decorations is a chemical manufacturing and often smell of hydrogen sulfide, then cross byblack almost certainly. However, this is the case, when the people's superstition is absolutely true: if you do not move away from the dangerous neighbourhood with an industrial facility, it may face trouble with health.
Least likely to blacken crosses, made in good jewelry shop of gold of high purity. The reason is simple. Jewelers value their reputation and don't try to cheapen their products by adding to the alloys of copper, Nickel and other "base" metals. Church of the master trying to make an inexpensive mass crosses, so often quality suffers.
Seeing that the cross darkened, do not panic. This is not mysticism and not the punishment of the Lord, and ordinary chemistry. You can clean the cross or to replace it with a more expensive one.
Do not buy a TIC from cheap alloys. Not only that, this product will darken quickly, it can still cause skin irritation.
Pectoral cross can be cleaned by putting in a jar with a mixture of tablespoons of water, a few drops of liquid dishwashing drops of ammonia and a pinch of tooth powder and soda. Putting the jewelry in the mixture, close the jar and vigorously shake it.
