The identification of gold jewelry
The identification of gold requires certain experience. Here are only some identification methods.
(1) See color: the higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so-called green gold contains only silver ingredients in gold); dark red yellow color is more than 95 %, light red yellow 90-95 % The pale yellow is 80-85 %, the cyan is 65-70 %, and the white light is only 50--60 % white light. The slightly yellow and white are less than 50 %. Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference. (2) Type weight: The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40 % heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, and the fake gold jewelry feels lightly. This method is not suitable for gold jewelry inlaid.
(3) Look at the hardness: pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave tooth prints. High -colored gold jewelry is low and soft, with copper with copper, contains copper containing copper, contains copper containing copper The harder, the harder, the bending method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend.
(4) Listening to the sound: Real gold with a color of more than 99 % throwing it on the hard ground, it will make a tap sound, there is no rhyme or elasticity. The fake or low golden sound is crispy but no dullness. Generally, the sound of "Dangdang" is emitted, and there are surplus sounds.
(5) Burning with fire: The jewelry will be burned red (do not melt the jewelry) with fire (do not melt the jewelry), and observe the color change after cooling. Dark or different degrees of darkness is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry.
(6) Seeing the mark: Domestic gold jewelry is allicized and prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; The word "18K" is marked, and those who have a lower color are lower than LOK. At present, illegal elements are commonly used to manufacture fake cards and imitation stamps in the society. They use rare gold, Asian gold, and even brass to impersonate real gold. Therefore, the identification of gold jewelry must be comprehensively determined according to the sample to determine the true and false and the quality of the real.
The platinum and platinum
In fact, it is simply that platinum is an element, and platinum is a mixture. Platinum: Platinum (PT), which is more stable than gold, and the price is more expensive than gold. It is used to make high -end jewelry. The "PT900" or "PT950" seen on the products of jewelry stores represents the content of platinum in the jewelry of 90 % and 95 %, respectively. The general purity of pure platinum jewelry is 95 %, while the purity of 18K gold is only 75 %. It is impossible for any metal to be completely pure, with impurities and mixed with other metals. Platinum has almost no impurities, and the purity is extremely high, so it will not fade or change color, and it can still be shiny in the passage of time. Platinum pure white luster can reflect the real light of diamonds. Rare platinum is 35 times more rare than gold. In the world, it can only be mined in very few places. It is mainly located in South Africa and Russia, as well as a few areas of Zimbabwe, Canada, and South America. Each year, only 88 tons of platinum is made into jewelry, while gold has 2700 tons. The number of platinum ore is less, the proportion of gold ore is 1 to 10. The density and weight of eternal platinum make it more durable than other jewelry metal. All valuable metals will leave scratches, and platinum is no exception. However, the scratches on platinum only move the metal and will not reduce its volume, and the gold scratches will bring wear and reduce the volume of gold. If there are indeed scratches on the naked eye on the platinum, qualified jewelry vendors can be polished for it. Platinum: a mixture containing gold (AU) and other amounts of other metals. The maximum purity of Platinum in the market is 75%. It is mixed with 75 % gold plus 25 % silver, nickel, copper and other metals, which is white K gold. The difference between 18K platinum, 750 platinum, 750G, etc. The difference between the difference between platinum and platinum platinum and white K gold is mainly to see the mark on the jewelry. The ring will be marked in the inner circle, and the necklace is marked at the buckle. Platinum jewelery of more than 990 ‰ of platinum is generally a "foot platinum" mark. The "P950" mark indicates a platinum with a color of 950 ‰. The white K gold is required to indicate the KK number. K means the gold content, such as 18K white, 750g, 750 gold, and AU750. The purity of platinum jewelry is not expressed as "K". The white K gold and K platinum jewelry sold on the market are not platinum jewelry. When buying platinum jewelry, you should ask the operator to issue an invoice. Write whether it is platinum or white 18K gold in the invoice. It is best to indicate the weight of the jewelry, so that it is easier to claim when the fraud occurs.
