The pricing method of gold jewelry

Weight measurement
The main units of measurement for measuring the weight of gold are ounces, grams, kilograms (kg), tons, etc. The commonly used unit of measurement for gold internationally is the ounce, and the world gold prices we often see are priced in ounces.
The gold traded in the European and American gold markets is measured in troy ounces, which is different from the commonly used unit of measurement in Europe and America, the troy ounce. The troy ounce is a trading unit of measurement specifically used for precious metal commodities such as gold, and its conversion is as follows:
1 troy ounce=1.0971428 troy ounces=31.1034768 grams
1 troy ounce=28.3495 grams
In China, it is generally customary to use grams as the unit of measurement for gold. Although the metric system is used domestically, this unit of measurement for gold in China is different from the customary unit of measurement "ounce" agreed upon in the international market. Domestic investors investing in gold must first adapt to the differences in this unit of measurement.
Purity measurement
The purity of gold and its products is called "purity", and there are two types of purity indicators for gold products on the market: one is percentage, such as G999; Another type is K gold, such as G24K, G22K, and G18K. China has regulations on the marking and identification of gold products, which generally require the production enterprise code, material name, content mark, etc. Without the mark, it is considered an unqualified product. The same applies internationally. But for some particularly small products, it is also allowed not to mark them.
