It has something to do with the brand you want to buy. For famous brands, such as Chow Tai Fook Chow Sang Sang Sang, now the gold is about 360 yuan per gram, plus the processing costs of necklaces, so you can buy about 27 grams of gold necklaces. If it is an ordinary brand, the price of gold is about 330 yuan, so you can buy about 30 grams of gold necklace.
The 10000 yuan gold necklace has 28.7 grams. According to the inquiry, the price of gold is 384 yuan per gram, and 28.7 grams of necklace can be bought for 1000 yuan. The gold necklace refers to the headpiece made of gold materials, which is usually hung on the neck for decoration. The famous one is the Persian gold necklace of the Sui Dynasty.
At present, gold costs about 300 yuan per gram. The gold used in gold rings is uncertain, and the purity is different;
用"k金"表示黄金的纯度:在理论上把含量100%的金称为24K;所以计算方法为100/24(括号内为国家标准): 国家标准GB11887-89规定，每k含金量为4.166666%，9k=100/24*9=37.5% (375‰);
14k=100/24*14=58.333%(585‰)，为方便标识，把它定在58.5%;
18k=100/24*18=75%(750‰);
22k=100/24*22=91.666%(916‰)，为方便标识，把它定在91.6%。
