24k yellow gold necklace and thousand gold necklace which is cheap
أيهما أفضل, 24ك قلادة من الذهب الأصفر وقلادة من الذهب ألف? هذا سؤال صعب. بعض الناس يحبون الذهب عيار 24 قيراط, بعض الناس يحبون آلاف الذهب. الفرق بينهما ليس كبيرا, والنقاء أسوأ قليلاً. If purity is not critical, الاثنان متماثلان.
my country has regulations on the marking and identification of gold products, and generally requires the production company code, material name, content imprint, إلخ., 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) يكون 4.166%.
من الناحية النظرية, we call gold with a content of 100% 24ك; 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%.
من الناحية النظرية, 100% gold can be called 24K gold, but in reality it is impossible to have 100% ذهب, so China stipulates: gold with a content of more than 99.6% (مشتمل 99.6%) can be called 24K gold.
آلاف الذهب: 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 ذهب, gold999 or g999. الذهب الصلب: The solid gold with a gold content of not less than 990. The imprint is “Full Gold”, “990 ذهب”, “gold990” or “g990”.
