Gold is the single form of chemical element gold (au), one of the rarer, more precious and highly valued metals. International gold is generally ounce-based, and ancient chinese gold is a very important metal。
When buying gold products, we often hear the words “foot money, k gold, 3d hard money, 5g gold, ancient gold” etc
Gold
The purity of gold is not 100 per cent. Gold is gold containing more than 99 per cent of gold and is more widely marketed. At the moment, we have eliminated the claim that the full amount of money, i. E. “three nines”, “four nines” and “five nines”, is only sufficient, at essentially the same price at the time of pawning/recycling。
K-gold
K (karat) is the term used in the jewellery industry to measure the purity of gold. K is preceded by a numeric reference to gold jewellery containing different proportions of gold, such as 9k, 12k, 14k, 18k, 24k。
Pure gold is 24k (i. E. 100% gold). But even if it's pure, it can't be 100% pure, so technically there's no 24-k gold. In our country, more than 99. 96 per cent of gold, including 99. 96 per cent, is called 24 k gold。
The common 18k gold on the market is 18*0. 04166 ≈ 75%. We do not call gold jewellery with a gold content below 9k。
3d hard money
3d of 3d hard money is the abbreviation of three-dimensional, meaning three-dimensional graphics. Gold jewellery, which is currently seen on the market, is mostly 3d hard。
3d hard money is still made of gold, with a gold content of 99. 9 per cent and above, and is full of gold. Traditional gold jewellery is softer and 3d hard metals are “hard” gold. The use of the "electric casting" model in the process increases the hardness of gold jewellery significantly higher than that of ordinary gold jewellery and is therefore more resistant to grinding and deformed scraping。
5g gold
Gold-decorative techniques have been modernized over generations and are becoming more sophisticated, with 5g gold being the product of the fifth generation of new gold processes. Unlike traditional gold production processes, the production of 5g gold products must be combined with both traditional gold and k gold production techniques, and the entire production line and processing process is the production of unsighted crematories. The 5g gold product can be created only if the gold material molecule is stabilized。
5g gold is very resilient, difficult to break, light weight and high hardness; it is process-advanced, fashion-style; and the most important purity is gold au999, which combines the hardness, purity and quality of gold material。
Ancient gold
The ancient gold refers to the manual fine sculpturing of gold ornaments through our ancient and traditional processing techniques. Processes include florist, carving, as well as fetters, hammers, embedding, gold repair, etc., many of which are already included in china's intangible cultural heritage. It requires a great deal of effort on the part of skilled craftsmen, so production time is usually dozens of times greater than normal gold。
The ancient gold is a return to the truth, giving people a sense of non-pretence and valor, and satisfying the demands of modern women for “gentle, noble and low profile”. The ancient gold has a higher sense of dumbness, a fine process and a good visualization, and the ancient gold is a golden process inherited from generation to generation, combined with a rich and deep chinese traditional culture, which is very chinese。
3d hard, 5g gold, and ancient gold are different processes for processing gold, and pureness is essentially full gold, and everyone can choose according to their needs。
