24k yellow gold necklace and thousand gold necklace which is cheap
Qaysi biri yaxshiroq, 24k sariq tilla marjon va ming tilla marjon? Bu qiyin savol. Ba'zi odamlar 24K oltinni yoqtirishadi, ba'zi odamlar minglab oltinni yoqtirishadi. Ularning orasidagi farq unchalik katta emas, va poklik biroz yomonroq. If purity is not critical, ikkalasi bir xil.
Mening mamlakatim oltin mahsulotlarni belgilash va identifikatsiya qilish to'g'risidagi nizomga ega, va odatda ishlab chiqarish kompaniyasini talab qiladi, Moddiy nomi, tarkib izi, va hokazo., va hech qanday izoh - bu malakasiz mahsulot emas. 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) bu 4.166%.
Nazariyada, 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%.
Nazariyada, 100% gold can be called 24K gold, but in reality it is impossible to have 100% oltin, so China stipulates: gold with a content of more than 99.6% (shu jumladan 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 oltin, gold999 or g999. Qattiq oltin: The solid gold with a gold content of not less than 990. The imprint is “Full Gold”, “990 Oltin”, “gold990” yoki “g990”.
