How can I determine if it is really gold?

My colleague bought a ring looking nice outside E * Bay, the vendor claims that is 22 carat gold. All I ended up paying $ 29 for the ring and say it is not possible. I felt the ring, and that feels about 15 grams. And, in fact appear 22 karat gold, but there is no mark of ingots sealed inside. If somehow this was real gold, I would like my friend might be interested trying to sell them at a higher price. But how can you determine whether it is real? I do not think that is a geologist for some type of trial is an option. Is there tell a story of things that can be detected with a magnifying glass perhaps, they would back someone that is real?

The lack of a hallmark (10k, 14k, 18k, etc.) no indication of whether your piece is gold or not. In the United States is against FTC regulations for the jeweler to hallmark a piece of jewelry unless it is accompanied by the mark of a manufacturer. So, when I started making jewelry and have a brand of mine, I my jewelry Hallmark. Now that I have a manufacturer's brand, Hallmark me my jewels with the appropriate metal hallmark and my maker mark. A jeweler can not just look at a piece and say with certainty whether it is gold or not, the jeweler will test to determine. scientfically To be exact a sample of the metal in question must be analyzed in a test lab, but the following two tests have been used for many years and are often sufficiently accurate for a craftsperson or the owner of the metal in question. To answer "Is it gold?": With a small file, make a scratch in an inconspicuous place. While the use of rubber gloves, use of wood, glass or plastic stick to apply a drop of nitric acid to the point presented. Observe the reaction. When done, rinse everything with water. If no reaction is gold. If there is a bright green reaction, it is base metal. If there is no green at zero, which is a layer of gold on metal (gold badge). If a galaxy reaction in the scratch, which is a layer of gold on silver. To answer "What Karat Is It?" Determining karat requires a testing kit containing nitric acid, aqua regia, samples of known karat, and a touchstone of slate or ceramic. The gold object to evidence are rubbed on the stone ( "touched") to leave a streak. A parallel line is made with one of the test pieces of known karat. Both brands are flooded with acid and the reaction is observed. When the sample colors in the same proportion as the test run, a match was made. Nitric acid is used for low karat gold, aqua regia is needed for more carats. Note: These tests are only for your information. They are not accurate enough to trust that represents a piece for sale. Most jewelers have testing kits to use to determine whether or not something is gold and its approximate karat. It is probably more easy to bring the issue to a jeweler in the creation of the test kits yourself.
