wholesale jewelry stores in new york (1) Seeing the mark: Now the gold jewelry produced by manufacturers in my country is made by purification according to international standards, and the marks are used to indicate the amount of gold in metal products with K. Foot gold is 24K, and the gold content is 99.6 %; 22K gold content is 91.3 %; the gold content of 20K is 83.3 %; the gold content of 18K is 74.7 %; the gold content of 14K is 58.5 %; It is 37.5 %; the gold content of 8K is 33.3 %; the gold content of 1K is 4.166 %. According to the words of 24K or 18K on the mark, you can know how the jewelry is in color, but the mark of K gold cannot be used as below 10K as regulations.
(2) See color: The higher the purity of gold jewelry, the deeper the color. As people often say "seven greens, eight yellows, nine purple and ten red", that is, if the gold decoration is blue yellow, the gold content can reach 70 %; the yellow content of yellow can reach 80-90 %; if it is red yellow, the gold content can reach more than 95. Of course, it is not enough to distinguish the color and true and false of gold jewelry by color.
(3) Type weight: The proportion of gold is 19.3, which is higher than other metals. The same volume of gold is 1.8 times the weight of the silver and 2.2 times the copper. Therefore, the real gold bearing should feel heavy in hand, and fake gold feels lighter.
(4) Listening to the sound: throw the gold jewelry to the desktop, or throw it on the hard ground. The lower the gold content, the greater the elasticity, the higher the jump, the crisp sound, and there is a tone; the higher the gold content, the higher the content of the gold; The smaller the elasticity, the lower the jump, the sound of the sound is low, heavy, and no sound.
(5) Testing hardness: The higher the gold content of the jewelry, the softer the more soft, and it is easy to bend with your hands, good toughness, and not easy to break. You will leave clear scratches with hard things; the lower the gold content, the harder it will be. It is necessary to use a large strength to bend, and it is easy to break. When the hard things are engraved, the scratches are not obvious.
(6) Scientific test: First, use fire to identify. Put the jewelry in the smoke -free fire, and the color is unchanged after the pure gold is burned; The second is chemistry. With a concentration of 45 % or 70 % sulfuric acid, the gold has no change and keeps the original; the silver becomes black; Because metals such as silver and copper are dissolved in acid, a chemical reaction will be developed.
