Most gold alloys contain some copper and silver. In certain conditions and over a long period of time, these will tarnish giving a duller and darker look to the gold. Silver cleaning products will remove the tarnish and restore the brightness. Another possibility is that the bracelet is not gold but gold-plated/gold filled brass or copper.

Silver Oxide forms on the surface. The only metal that does not Oxidize is Gold.
No, you cannot turn yellow gold into white gold. White gold, yellow gold, and rose gold are all alloys of pure gold. You can only turn pure gold into white gold.
Gold Filled: Gold filled is an actual layer of gold-pressure bonded to another metal. Gold filled is not to be confused with gold plating as filled literally has 100% more gold than gold plating. Gold filled is much more valuable and tarnish resistant. It does not flake off, rub off or turn colors. As a matter of fact, anyone who can wear gold can wear gold filled without worries of any allergic reaction to the jewelry. Gold filled jewelry is an economical alternative to solid gold!

Can silver and gold give you a shoulder to cry on, a laugh to share? Can you confide in silver and gold and comfort them in your turn? Silver and gold cannot, absolutely cannot, give whatever a good friend can give.
Gold-tone over base metal is not the same as gold. Silver-tone over base metal is not the same thing as silver. Many base metals are used to make jewelry, and they are often coated with paint to make it look like gold or silver, but once the paint wears off, the metal can react with the skin and turn it green. This is especially true of jewelry that is made of copper and then coated with paint. Copper reacts to the sweat in a person's skin, and turns green. Gold-filled and gold-plated jewelry may also have certain base metals that react with a person's skin. The same is true of silver-plated and silver-filled. Sterling silver, Bali silver and such are not reactive and should not turn the skin green. Gold should not turn the skin green. Electroplate is another way of fusing gold or silver to base metal, and it is very durable, but if the plating ever cracks, the base metal could be reactive with the skin. The way to avoid purchasing something that will turn your skin green is to check for the tiny stamp imprinted on gold (it will tell how many carats of gold the jewelry is made of) and sterling silver (it will say sterling, and perhaps be accompanied by some numbers).

Fake metal can turn your skin green this applis to gold and silver.
No, silver is very similar to gold and is not magnetic. It does not turn magnetic on its own however in a magnetic field it magnetizes to a very little extent.
Theres a guy in the pewter museum who will turn your fossil into pokemon.
