Types of gold: Which is better, 3 9s or 4 9s?

Gold is an ornament with great appreciation value. The purity of gold also determines the color, appearance and price of gold. There are more and more gold jewelry brands on the market. When choosing, you should pay attention to choosing regular big brands.

Gold can be divided into pure gold, 999 gold, platinum, 3D hard gold, K gold, gold-plated, colored gold, etc. according to the jewelry that is usually purchased. If it is divided into paper gold, spot gold, futures gold, physical gold, gold T+D, gold prepayment, people's livelihood gold, etc. according to the investment of gold. K gold can be divided into 24K, 22K, 20K, and 18K. The gold content ratio of 1K is about 4.166%, and the gold content of 24K is 99.99%, which is generally called pure gold. In normal times, 4.166% can be multiplied by the K number to get the gold content. Generally, the less the gold content, the more the shape of the handmade jewelry. When buying gold jewelry, you must distinguish the authenticity, and you need to master certain methods here. The simplest method is to burn it on the fire for a while, and then observe its changes. If the purity of the gold is not enough, it will turn gray, and the color of pure gold will be bright red after being roasted by fire. Note that this method may damage the jewelry. If users want to invest in gold products, they should be patient when investing at this time, and don't think about getting rich profits immediately after investing. In the process of trading, you must learn to control your emotions and be prepared to deal with various situations. For example, when you are bullish, you must be mentally prepared for a decline, because nothing is absolute in the world and the market is always right.

First, the main difference is the purity. 999 means the gold content is 99.9%, and 9999 means the gold content is 99.99%. However, when making jewelry, it is difficult to achieve 99.99% because gold needs to be welded during the production or processing process. Generally, 99.9% is the highest.

two,

1. Myth 1: The higher the purity, the more expensive the price

Pure gold is generally priced based on the international gold price, and then a certain amount of processing fees, rent, labor, etc. are added, and finally the price is calculated by gram; although 18K gold is also affected by the international gold price, the labor and design fees are higher than pure gold, and it may also be inlaid with other gemstones, so the price is usually sold at a fixed price and has no direct relationship with the weight of the gold.

2. Myth 2: The higher the purity, the more valuable it is

The saying "the higher the purity, the more it retains its value" is basically correct, but the current situation is that Chinese people like to pursue the ultimate in "purity". They think that pure gold is not pure enough, so they pursue 999 pure gold; one day they think that 999 pure gold is not pure enough, so they pursue 100% pure gold. The recycling price is also calculated uniformly according to the recycling price of pure gold, so there is no such thing as 100% pure gold retaining more value than 999 pure gold or 999 pure gold retaining more value than pure gold.

3. Myth 3: High-purity gold will not fade

Pure gold is indeed less likely to fade than K gold, but many people find that pure gold rings and necklaces will fade after wearing them for a long time. In fact, there are many reasons for them to fade, such as chemical reactions caused by contact with human sweat, daily chemicals, etc., especially after contact with things containing chemicals such as mercury. These are all normal phenomena, you can send them to the merchant for refurbishment, and you should also pay more attention to maintenance.

2. Gold content: The gold content in jewelry is an important indicator of its quality. There are many ways to test the gold content, which can be divided into chemical analysis methods and instrumental analysis methods. According to whether the jewelry is damaged during the test, it can be divided into non-destructive testing methods and destructive testing methods. The daily inspection of jewelry quality supervision departments generally focuses on non-destructive testing methods, density methods combined with X-ray fluorescence spectrometry, electron probe and other large-scale instrument analysis. Market supervision and random inspections are mainly based on destructive testing. The fire assay method is a national test method for determining the gold content in jewelry.

3. Pure gold: Gold with a gold content of not less than 999.9 is called pure gold, which is the highest value in the naming of jewelry purity in the market.
