Many people who have an interest in gold jewelry and coins often say that gold spotted there, however, that is as far from the truth. Pure gold will not tarnish, but it is rare to find jewelry that contains this pure element. When gold is added to gold alloy as the 18 carat or more, it also decrease the risk of blur, with the exception of a few conditions. Tarnish usually only seen in small carat, depending on the base metals and elements that each one is exposed. For example, if a coin 10 karat gold has a decent amount of copper in it, they can oxidize, creating a red or black tarnish. Silver also exposed to the elements when combined with the black gold produces pigmentation.

So what causes spotting gold? When gold is mixed with these base metals, as almost always, exposure to environmental factors that will have an effect on metals. The humidity, organic vapors, and oxygen compounds sulfur in the atmosphere, and even human sweat and oil from human touch can tarnish gold when mixed with a lot of base metals. Surprisingly, the perfumes and deodorants with certain chemicals in them can also affect gold to a point that will tarnish.

One of the most surprising offenders gold is tarnish because of certain foodstuffs. Pickles, fruit juice, onions, and other items with high acidity or sulfur compounds can create an effect tarnish the gold that is less pure.

Some countries like India and Middle East countries not experience a darkening of the most high-karat gold, and nobody seems to know the cause. In general, relates to a different lifestyle and environmental conditions or environment, since the problem does not occur elsewhere in the world, but nobody knows for sure.

When it comes to coin collecting, which many consider a little tarnish, or tone as it is called in collecting circles, to be highly desirable. The rare gold coins tarnish because of its purity, but there are some coins exceptional tone and this makes the tone much more valuable. You may want to clean your jewelry to have it restored to its original shine, but all collectors know that never, never clean the tarnish off your coins. In fact, it a general rule of not cleaning the coins in any way. Collectors will of the antique look of an old coin and wants to see preserved. Cleaning gold coins highly collectible can ruin its value.

Just remember that is perfectly fine to clean tarnish off your beautiful jewelry, but never clean the tone off of valuable old gold coins. Stick to these rules and keep your valuables in gold of any kind in the best conditions and highest possible value.
