Sadece bakarak bir şeyin altın olup olmadığını söyleyebilir misin?
The short answer NO. Gold comes in different forms and percentages. Gold plating can look very real. Good fakes or costume jewelry, can be very deceiving. What about jewelry marked with the karat weight like 14 KT, is not necessarily good either. I have a gold buying business that buys scrap or unwanted jewelry. We literally see every day, pieces with the karat weight clearly marked but after testing it is not real. There is a large number of companies that import jewelry that is clearly marked but not real. People will say”isn’t that illegal”? Kuyu, Evet, but so are many other things that are shipped into this country, like drugs, illicit recordings, even money. Yes we frequently get fake Silver Dollars or Silver Rounds, they look real but when tested with a magnet they stick very tight. Many of these are copies of early Silver Dollars like the 1935 Peace dollar. The simplest test you can do at home is place a magnet over it. If it sticks to a magnet, “IT IS NOT REAL”. There are many metals that will not stick to a magnet, Alüminyum, yol göstermek, Gold and silver. You probably learned this in the third grade. So the answer is be careful, have a jeweler or pawn shop or gold buying company to check it or test it. Many of these type companies will do this for free. Especially for those that are good customers.
Do not buy a gold piece of Jewelry at a Gas Station or in the Wall Mart parking lot.
