24k yellow gold necklace and thousand gold necklace which is cheap
Που είναι καλύτερο, 24k yellow gold necklace and thousand gold necklace? This is a difficult question. Some people like 24K gold, some people like thousands of gold. The difference between them is not great, and the purity is only a little bit worse. If purity is not critical, τα δύο είναι τα ίδια.
my country has regulations on the marking and identification of gold products, and generally requires the production company code, material name, content imprint, και τα λοιπά., and no imprint is an unqualified product. The same is true internationally. But for some very fine products, it is allowed not to mark. National standard GB11887-89 stipulates that the gold content per opening (abbreviation of carat in English and karat in German, writing K) είναι 4.166%.
In theory, we call gold with a content of 100% 24K; so the calculation method is 100/24 (the national standard in parentheses): the national standard GB11887-89 stipulates that every k (abbreviation of English carat, German karat, often written) “k”) The gold content is 4.166666%.
In theory, 100% gold can be called 24K gold, but in reality it is impossible to have 100% χρυσός, so China stipulates: gold with a content of more than 99.6% (συμπεριλαμβανομένου 99.6%) can be called 24K gold.
Thousands of gold: Thousands of gold with a gold content of not less than 999 is called thousands of gold, which is the highest value in the name of jewelry. The imprint is thousands of gold, 999 χρυσός, gold999 or g999. Solid gold: The solid gold with a gold content of not less than 990. The imprint is “Full Gold”, “990 Χρυσός”, “gold990” ή “g990”.
