Pay content for time limit to check for freenAnswer Hello, the gold purchased by Lao Fengxiang store is really specific to the label. As a century -old national brand, Lao Fengxiang's gold jewelry is undoubted. After all, no brand will make a joke with his own brand. Founded in 1848, Lao Fengxiang developed from Lao Fengxiang Yinlou. So far, it has a history of 168 years. As an old brand, it will inevitably be more attentive in terms of product quality and reputation.nAsk the introduction of Lao Fengxiang R FI GoldnAnswer the pricing of gold jewelry is divided into fate F (pricing foot gold) and R (one -bob)nThe gold content is not less than 99 % called foot goldnThis means a gold -based gold with a gold content of not less than 99%nAsk Lao Fengxiang R's gold is the amount of gold with only half of the purity.nThe answer is not, the gold content is full gold, and the words of foot gold are not less than 99%of the content.nAsk how much it looks like, is it more cost -effective to buy 9999 or 999 or R FI Gold.nThe answer is 99%. This mainly depends on the gold contentnWhat are the differences between asking the price? Can you introduce it? Thank younAnswer 999 is thousands of gold, and the purity of gold is 999; 9999 is a 10,000 -footed gold, which means that the purity of gold is 10,000 per 10,000, which is 9th of 10,000. The difference between gold 999 and 9999: Different word printing is different. The national standard stipulates that the gold jewelry content seal is sufficient gold. The gold content must reach more than 990%. 999 gold and 9999 gold cannot see any difference in appearance. The same gold shop 9999 gold price is higher than 999 gold 10 to 30 yuan/gram.nJudging from the gold content (purity) of gold, 999 gold is different from nine ten thousandth of golden purity between 9999 gold. Of course, if in the gold bars, 9999 gold is naturally higher than the gold content of 999 gold. If it is in jewelry, then the 9999 gold jewelry does not exist. After all, gold jewelry needs to be welded. Essence Therefore, it is naturally better to be 9999 gold if it is collected by gold bars alone.nAsk Question that RF is 999, or less than 999, what's the difference, thank younThe answer is 999nAs mentioned above, it is 999999nQuestion, thank younAnswers are politenMore, you can compare the price in the store yourselfnMore 16nBleak
Lao Fengxiang's gold ring, in general, if it is normal channels, there will generally not be fake. The method of distinguishing authenticity: . Look at the color Gold, K gold, real gold, fake gold. That is, gold is better with red yellow, and the color is more than 95%; the positive yellow color is about 80%; the blue and yellow color is about 70%; the yellow color is slightly gray and the color is about 50%. Therefore, there is a formula for "seven greens, eight yellow, nine five red, and yellow leucorrhea ash. For jewelry from Jiu Tibet, there will be a saying that "copper turns green, silver turns black, and gold will never change color". . Folding hardness Gold has the characteristics of ductility and small hardness, and can be pressed into thin pieces of 12.7 microns. When the color is high, marks can be left with large head needles or nails. More than 97%of gold jewelry, after twisting two or three times, wrinkles appear at the bending, also called fish scales; about 95%of gold jewelry, it feels hard when bending, and the fish scales are not obvious; about 90%of the golden gold golden gold; The jewelry is very hard when the bending is bent, without fish scales; gold jewelry containing more impurities, bend twice or three times to break; if it is made for raw gold, the bend is broken. When using this method, the width and thickness of the jewelry should be considered. The thick and width should be hardened, and the thin and narrow ones are softer. . Listening to the rhyme, watching elasticity When the high -quality gold jewelry is tapped or thrown into the hard manner, the dull sound of "dwelling, clocking" is emitted, and there is no rhyme, no elasticity, and no elasticity. K gold has sound rhyme, sound, elasticity, the greater the elasticity, the more the rhyme, the more old, the worse the color. . View density The density of gold is 19.32 grams/cubic centimeter, which is about double the same volume of silver, lead, and tin. Available formula: The mass (gram) of a certain gold jewelry (gram) is equal to density than the volume (cubic centimeter) of a certain gold jewelry (cubic centimeter). Seeking the density of the gold jewelry measured, the density is about 19.32 grams/cubic centimeter, it is pure gold or more pure gold, otherwise it is a non -pure gold or color difference gold (this method has no destructiveness to the jewelry). 5. Use the test goldstone to identify the color The use of the gold -pairing card (the gold medal identified in color) and the subject's first jewelry on the test gold stone to make the color of the gold jewelry. This method should be carried out under natural light and sunlight, and cannot be carried out under the direct sunlight and incandescent lamps. . Use acid dot The golden roads that have been identified and paired on the testing stone, respectively, and test nitric acid on the golden road with a glass stick. , So the color is unchanged. If it is not gold or non -pure gold, the Golden Road disappears or changes. The law of changes is "three fast, three slows", that is, the low color disappears quickly, and the high color disappears slowly; Depending on the disappearance of its golden road, compare cards can determine the color of gold jewelry.
