Recently, my little friend is getting married, thinking about buying a ring, and when I went to the counter, I was confused by the material of the ring. I was stupidly confused about the difference between 18k gold and platinum. Although the shopping guide introduced her to her again, Still unclear. So today, I’m mainly from the material. Recently, my partner is getting married. I was thinking about buying a ring. When I went to the counter, I was confused by the material of the ring. I couldn’t tell the difference between 18k gold and platinum. Although the shopping guide girl and her I introduced it again, but it was still unclear. So today, I will introduce the difference between 18K gold and platinum mainly from the three aspects of material composition, price, and inlay material.　　　　 1. Material composition difference 　　　　 18K gold on the market refers to an alloy of 75% gold and other 25% precious metal elements. The color of 18K gold is richer, including white, rose, yellow, purple, blue and other colors. These 18K golds with different colors are synthesized from different precious metals according to different proportions. The matching ratio is as follows: 　　　　18K blue gold: 75% + iron (appropriate) 　　　　18K black gold: 75% + thick iron 18K purple gold: 75% + lead 18K yellow gold: 75% + nickel + silver + zinc 18K rose gold: 75%+copper+silver+zinc 18K white gold: 75%+silver+nickel+platinum+zinc or 75%+palladium, it is slightly bluish white, usually white and rose gold are more common Style colors, blue, purple and other colors are generally creative styles designed by independent studio designers.　　　　Platinum is a naturally occurring white precious metal. The color of platinum is very similar to that of 18K white gold, both of which are white, but platinum and platinum are two different materials, and there is a big difference in price.　　　　 Platinum and 18K white gold can’t be recognized by the naked eye. They can be distinguished by signs. Platinum is represented by Pt, such as Pt950, where 950 means that the platinum content in the jewelry is 95%. The imprint of 18K gold is 18K, AU750 or G750. Usually the material of the ring is marked on the inside of the ring, and the mark of the necklace is on the buckle.　　　　Second, the difference in price　　　　We often see the same style of jewelry in counters. The price of platinum is higher than that of 18k gold. This is because 18K gold is an alloy, so the price is much cheaper than platinum.　　　　 Platinum is very rare, and its concentration in the earth's crust is only 0.005 parts per million. There are only a few areas in the world that can be mined, and the mining is extremely difficult. The extraction of platinum is also more difficult than gold. It takes about 10 tons of platinum ore and 8 weeks to extract 1 ounce of platinum, while it takes 5 days to extract 1 ounce of gold. time.　　　　In terms of recycling value, 18K gold is more popular than platinum, because platinum is not a hard currency and the recycling loss is greater. 18K gold has the value of gold and there are many recycling channels. Generally, ordinary gold shops can recycle it. 3. The difference in the choice of inlay material 1. The hardness and ductility of metal made of 18K gold is higher than that of platinum in terms of material. It can fully meet the needs of inlay, and it has more creative expression in the design of jewelry. Platinum on the contrary. 2. The color of 18K gold is relatively rich, and the space for selection is relatively large. Different colors of K gold can choose different gems. For example, white K gold is more suitable for cold-toned gems, and yellow K gold is suitable for warm-toned gems, such as red. Drill. Rose gold and K gold are more suitable for inlaid gemstone colors, which are popular colors on the market now.　　　　3. Although platinum has high purity, 18K gold has high hardness and is not easy to deform, so it is not easy to loosen when inlaid with gemstones and is stronger than platinum.
