4 thoughts on “How to distinguish the texture of platinum and gold in jewelry stores?”
Earnest
The gold making jewelry is not pure gold, because the pure gold is too soft to go through wear. Therefore, since ancient times, most of the pure gold is mixed with other metals and used to make gold jewelry, called "decorative gold". The pure gold content unit in the jewelry is called "gold". The English is called "Carat", which is generally called "Kai". Pure gold is 24K. 1K means that the amount of pure gold contained in the gold jewelry accounts for one -twenty -four -in -one. 14K means 58 % of pure gold. In the UK, the gold jewelry is 10K, 14K and 18K, and only a few are 22K. In Europe, gold jewelry is generally 14K, 18K and 22K. In France and Sweden, the minimum standard is 18K, and Switzerland, the Netherlands, Belgium, Luxembourg, Norway, and Denmark stipulate that gold jewelry must not be less than 14K. West Germany and Italy were less than 8K. Gold jewelry has various K numbers and various colors. Mixing gold with copper, silver, nickel and 钯 of different grades is green.
The identifiable general methods of gold and falseness include four types: color, pivotal, seeing rhyme, and testing soft and hard. In addition, there are four types: there are four types of throwing method, burning test method, reagent method, and viewing the printing marker method. The following introduces the following:
1) Different color: As the saying goes, gold is "Qiqing, Eight Yellow, Nine Purple, Ten Red", which presents different colors because it contains different types of impurities and ingredients. The experts believe that the jewelry of 70 % of the gold is yellow, 80 % of the gold, and the golden gold, and the gold is 90 % of the yellow medium purple, and the gold is 10 % red. The pure gold is soft, and it is generally not used to make embedded jewelry. Therefore, all inlaid gold jewelry claims to be 24K and there must be fraud. 2) 重 重 The proportion of gold is 19.3g/cm³, and the proportion is more related to the proportion. When the proportion is close to 19.3, the higher the pure gold. At 18.5, the gold contains 95 %, and the gold contains 90 % at 17.8. As long as the proportion is measured, the color of the jewelry can be seen, but it can generally be in the hands. If there is a slightly heavy feeling, it can be perceived, because other metals with the same weight, such as silver, copper, tin, lead, etc. the same. Compared with other metals with the same size, silver accounts for 45 % of the gold weight, copper accounts for 46 %, tin accounts for 38 %, and lead accounts for 59 %. It can be seen that the gold body is small and heavy. You should be vigilant for the stupid and light jewelry, and carefully discern whether for fakes or semi -fakes.
is worth noting that many of the golden jewelry sold in the current market are Asian gold products. The so -called Asian gold is actually a little bit of gold. It is a alloy material made of metal such as copper, aluminum, nickel, and has the characteristics of high hardness, abrasion -resistant and color -resistant color. 3) See the rhyme The high -colored jewelry, thrown on the cement floor, there will be dull tabs, sound without rhyme, no strength, commonly known as dead sound. On the contrary, the low -collision gold jewelry is thrown on the cement floor with rhymes and sharp sounds, and a slight jump. 4) Try soft and hard The higher the color of the gold jewelry, the softer, and the more elasticity. The real gold bite or the needle will have light marks. High temperature) will not change color afterwards. Low -colored and fake are the opposite. 5) Throwing method The real gold is thrown on the desktop and the ground. The sound of "click", and the fake or color difference makes a sharp and crisp sound. 6) Fire Burning Test Method "Real Gold is not afraid of fire refining", that is, it does not fade and insoluble at a high temperature of 1000 ° C. At 1063 ° C, it starts to dissolve but does not change color. Put the gold jewelry on the furnace surface or the tiles to bake until red. After cooling, the surface color remains unchanged. 7) Reaging method is to test with 45 % nitric acid: gold has no change, silver becomes black, and copper is green foam. This is because the chemical properties of gold are stable and will not be oxidized in any state, and it is also very stable in water, air, hydrogen sulfide or salt, or alkaline environment. Gold is soluble in any kind of single acid, which is only dissolved in the king water (the volume of the volume of the hydrochloric acid and nitric acid is based on a mixture of 3 to 1). 8) View the printing mark The gold jewelry produced by regular production plants, all covered with gold content and production plant marks, such as 24K and 14K. If a journalist is not the standard, it is generally a fake.
The authenticity and color identification of white gold jewelry 1) See color test according to the color level, generally divided into three colors, blue and white gray is high in color; Blue and white yellow is the ingredients of gold or copper in platinum, which are more colorful; silver is a lot of silver components in Platinum, which is lower than the above two types. The fake person is black. 2) Burning test Platquinity is placed in general furnace fire, and it can only burn red and not melt. After burning, the color is more than 95 %, the color is shiny, and the brighter the more burned, and the color is slightly black with a color of about 70 %. The fake becomes dark and it is easy to melt. 3) Test the weight and proportion test The proportion of Platinum is the crown of metal 21.4, which is 10 % heavier than gold, and heavier than other metals. The fake is low. Further than the proportion test, the specific method is the same as the proportion test of the gold. 4) Listening to the sound rhyme test pure platinum, knocking after the fire, making the sound of "Tobto", there is no rhyme, and the "Ding Ding" is pointed. rhyme. 5) See the test of the stubble This cutting the jewelry halfway with the mule halfway, and then the cotton (sticky) stubble occurs after bending. The higher the color, the softer the stubble mouth, the softener of the colors, and the shade of the color is sand -shaped, and it feels crispy when cutting. 6) Bend to see hard and hard Platinum is like gold, which has good ductility and can be poured into a platinum foil with only 0.0025 mm thick. The page paper is so thick. Therefore, bending hard and hard can also be used as a test method. 7) Trial of nitric acid adding salt points grinding the platinum on the test gold stone, add a small amount of salt to the platinum road (cover half of the golden road), then add nitric acid to the salt, add salt to the nitrate thoroughly through the nitrate thoroughly. The degree of level is 15 points, rinse salt and nitric acid with water. If it is Platinum, more than 95 % of them, the golden road remains unchanged, about 90 %, the golden road changes slightly, the micro -display is about 70 %, the golden road becomes black and gray, and it is corroded by a layer. 8) Mercury trial The scientific name of mercury is mercury, commonly known as mercury. Using gold and silver to absorb mercury, platinum does not absorb the characteristics of mercury (under normal temperature), coated with mercury on the golden road. If it is not absorbed, it means that it is real platinum. 9) Point gas lamp test M platinum has the effect of matching, which can be used to test the authenticity of platinum. The gas lamps are all under the match. If a real platinum is placed in the gas lamp product, after one or two cents, the platinum is red and the gas lamp also lits. If the platinum is fake, it will not be red, and the lights will not be ordered.
This is because Platinum has the characteristics of accelerating many chemical reactions. It can be used to catalyze. Oxygen in coal and air is difficult to directly combine. , Release a lot of heat, make the platinum block red, and finally light the gas light. 10) Bi peroxide test . It is a powder like platinum. Put a little in hydrogen peroxide. It is a real platinum. Immediately the white waves roll and decompose a large amount of oxygen, but the platinum powder is a lot at all. If it is fake, you can't afford to change.
In specific identification Platinum, the above methods can be used in combination. After careful research, it is determined.
Well, this question is good, let me tell you first ~ Now most of the market is PT950 (optimistic, PT is not a PD, now many small gold shops are sold as PT as PT) and there are a small part of a small part of it. It is PT900, which are all marks on the jewelry. With this mark, it will not be false. It is a problem of insufficient color. This problem generally appears in the small gold shop, because when the insufficient color will enter Cheap ~ Give you a few marks (BJ/Rongjin) that produce a large platinum manufacturer, and there will be no problems with this mark. Gold, now divided into two types of color (foot gold/thousands of gold) enough gold content is 99% gold, which is 99.9% when purchased. Do not listen to the salesperson. You said that his gold content is 4 9 Or 5 9 because this gold does not exist or not believes that you let him write you 99999 on your credibility card or invoice. He will definitely not write it for you Now you are saying that 18K gold should not think of white 18K All 18K gold in platinum is gold (including white). Now I talk about the specific gold content of 18K (75%of gold 25%copper/zinc/nickel/silver) due to the different content of the next 4 elements. The color you do is particularly good -looking In what you want to know ~ You will ask ~ as long as it is the
of the jewelry: | | Data 覌 覌 秂 秂 秂 秂 秂 秂 秂 秂 秂 秂 秂 秂 秂 秂 ..!
If you buy gold, it is best to choose a big brand to buy, (because the gold itself is really expensive ...), and the price of gold is uniform, each store is different, the processing fee is the processing fee Whatever or after -sales service, so I advocate that I still have to go to the brand store for safety. At the same time, there will be marks like "750 (18K), 999" on the gold; There will be marks such as "925", and it is also best to go to a special silver jewelry shop to buy. By the way, the highest state of silver is "925". There is absolutely no sterling silver ~!
