Buying gold always becomes an event, because many of our memorable milestones of life are accepted to celebrate such gifts. Wedding rings are the symbol of marriage union. A strip of metal envelopes the fingers of the beloved in the sign of infinity and harmony of their union. The anniversary of the pair is a necklace or earrings for the wife. The birth and age of the daughter-a pair of earrings with a pebble or bracelet. Baptism is a golden chain of crosses. For all our life we accumulate jewelry, looking at which we can tell a lot about our lives. They can go to our children and grandchildren as family, or help the family in the era of financial crisis or misfortune of someone close. All these situations are true only in the case when in our box is stored genuine metal. Many do not know how to check the gold for authenticity, focusing only on the reputation of the jewelry house, the advice of friends and aesthetic component, but it is quite feasible by yourself.
Whether you are a real gold and what level of quality you can learn in two cases-before buying or at home inspection. If you are going to buy a particular product, you should know its composition, weight, year of manufacture. Modern products are easier to classify, they have all the necessary markings, and their composition meets modern standards. Old gold, can be marked with ancient markings, and the designations can be specially jammed. To know how to determine the authenticity of gold, you need to familiarize yourself with the main characteristics of the real dragmetal.
To determine the characteristics of gold jewelry is quite simple, because it is marking. It can be a sample in numerical value or carats. The designation is performed from the inside of the rings, on the chain clasps, on the back side of the earrings, on the back of the pendant. If you have poor eyesight, you can take a magnifying glass to study such small details. You have to consider the state stamp, which will consist of several elements-the code of public. Inspection of the assay, the sign of the assay certificate, in the form of emblem, metal sample. In the territory of the Russian Federation is a trial, not a carat system of symbols. So, if you see these designations, you probably can believe them. Sometimes the attackers forge and stamp, so just in case you need to conduct a visual inspection of the product.
True gold can be of different shades, it does not mean that it is fake, perhaps you have a decoration of rare alloy-white, pink, green gold. These species have characteristic ebb.
Sometimes the jewelry is only sprayed with gold. It provides reliable protection to the main metal, which can not boast the same resistance to the external environment as gold. To understand that you have in your hands only a gilded product, carefully consider all bends, because the real gold can not be lost or contain stains. This method is especially effective in relation to chains.
If the product is from your grandmother, girlfriend or simply found in a drawer chest, you better try to determine its authenticity at home, to know whether it makes sense to go to a jeweler or a pawn shop. Options like check gold for authenticity without special training, a lot, can apply a few, then the result will be more accurate.
The old and revealing trick is a sample of a bite. You clamp a flat piece of jewelry with your teeth, press, and then see if there is a trace from the teeth on the surface. The way is controversial, because not every tooth can withstand such an onslaught, and not every alloy is so easily deformed. However, this method can be applied to investment coins, because they contain on 99% pure gold, and therefore-rather soft.
Checking can be quite simple, if you have in your hands is not just bad gold, and quite cheap counterfeit with the content of gold. In this case you will need a real strong magnet, which you need to bring to the decoration. If it is gold, it does not react and will not be attracted to the magnet.
Your jewelry should be put on a plate and held on it as a track. If it leaves a golden footprint, it is a genuine noble metal, if black or grey is a forgery.
You can arrange a check with a pencil, which can be purchased at the pharmacy. The product should be wet in water, and then draw with this pencil a small dash on the wet surface. After that take a cotton-wool disk and wipe a place of drawing. If there is a trace on the surface, and the rules of the test you do not violate-it’s fake.
Knowing how to act, you can check whether the real gold is even using iodine or vinegar. From these substances the forgery darkens and will spoil. It is necessary to take into account some peculiarities of gold, from iodine may appear gray speck, as a plaque, which can no longer be removed. Vinegar is harmless enough and usually used for cleaning, but if you want to still wear the product, even if it proves to be a forgery, it is not necessary to apply immersion in vinegar.
You can learn not only how real gold is in front of you, but also what the gold content is compared to impurities. To do this, you will need the exact weight of the product, which can be found through the apothecary weights. Knowing the weight in grams, find a bottle and fill it with water. It is better if it is a capacity with a division of Millitra, which is sold in a pharmacy or attached to household chemicals. Measure the height of the water level, which can be arbitrary, and immerse the product in the container.
Measure the distance from the original to the current water level. Further calculations are required. Look at the markings in carats, if there is only the designation of the sample, translate it into carats. Collect the gold weight for your product for the original data. If this gold is 24 carats, the weight should be 19, 3 G/MLE, 12 carats-approximately 17.7, 18 carats-from 14.7 to 16.9. The initial weight of your product must be divided by changing the water level (for example, by 2-3 millimeters). The obtained result must coincide with the requirements for the gold sample, if all is gone-you are the owner of real Gold.
There are more scientific, rather, laboratory ways of determining the quality and authenticity of precious metals. To apply them at home is not only difficult, but also dangerous. Knowing how to identify a forgery, you will never make a mistake with your purchase and recognize the real gold without problems. The listed household methods are time tested and effective.
