24k yellow gold necklace and thousand gold necklace which is cheap
Που είναι καλύτερο, 24k κολιέ από κίτρινο χρυσό και κολιέ από χίλια χρυσά? Αυτή είναι μια δύσκολη ερώτηση. Σε κάποιους αρέσει ο χρυσός 24 καρατίων, σε κάποιους αρέσει χιλιάδες χρυσός. Η διαφορά μεταξύ τους δεν είναι μεγάλη, και η καθαρότητα είναι λίγο χειρότερη. 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%.
Θεωρητικά, 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%.
Θεωρητικά, 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.
Χιλιάδες χρυσάφι: 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”.
