1.Test gold by looking at the "gold" in the sun. Gold should retain its color in the sun as well as the shade. Many metals glitter in the sun, but gold isn't one of them.

2.Stick a sharp needle or pin in the gold. If it fractures or cracks, it isn't gold. Gold is malleable, meaning it can bend and be dented but it doesn't crack easily.

3.Gold is heavy. It will sink to the bottom and stay there. If you are gold panning, a great test is to rock the pan back and forth with some water. Gold should stay at the bottom and not move around much.

4.A sure-fire way to test gold is to wear it on your skin. If your skin turns a greenish color, that isn't gold you are wearing, but more likely another metal with possibly a bit of gold content. A pure gold piece of jewelry will not react with skin.

5.Try running a magnet over the "gold." Precious metals like gold and silver are not magnetic, so if your "gold" is attracted by the magnet, that isn't a good sign. Of course, if it isn't, that doesn't guarantee it is gold. Lots of things are nonmagnetic, like wood.

6.The best way to test gold is to take it into an expert to be tested. Experts have sophisticated acid tests that can determine the exact gold content and tell you the gold price per gram and how much your item is worth.

Hard carbides, especially tungsten carbide, are used by athletes, generally on poles which impact hard surfaces. Trekking poles, used by many hikers for balance and to reduce pressure on leg joints, generally use carbide tips in order to gain traction when placed on hard surfaces (like rock); such carbide tips last much longer than other types of tips.

b) While ski pole tips are generally not made of carbide, since they do not need to be especially hard even to break through layers of ice, rollerski tips usually are. Roller skiing emulates cross country skiing and is used by many skiers to train during warm weather months.

Are you looking to make a purchase or sale your gold and want to know if it is authentic. This can be a difficult process but if you follow these easy steps you will know that you are buying the real thing and not waste your money.

1.First thing you should do, which is the gold check must, is put a magnet to the gold and if it sticks you do not have real gold on your hands. Real gold is not magnetic and some of the fake gold substances are made out of this magnetic silver alloy or other metals. Gold Dealers typically use this method first.

2.Next step is to get a 10 times magnifying glass and check the edges and crevices to see any cracking or discolloration as if there were two different surfaces. Gold will not chip and wear becasue it is solid all the way through, however you may have something that is gold plated so you should not discard because it could have real value.

3.The next step is if you happen to be lucky your piece would have been stored in a container because if there is a green or black residue left behind it can be a good sign that you do not have real gold on your hands. Be careful because some rings and watches are ingraved with the 14k gold, 18 karat, and 24k gold but this can just be a stamped in symbol and I have dealt with this many times and is not a good way to judge your product.
