Jewelry prices in gold jewelry stores fluctuate with the fluctuation of international gold prices every day. No matter how the international gold price fluctuates, the prices of traditional brands like Lao Fengxiang and Lao Miao are the same. Therefore, how they calculate the price formation process can be ignored.

2. About labor costs:

The calculation of gold shops like Laomiao Laofengxiang is like this. For example, today's international gold price is 260 yuan/gram, and the prices of these gold shops will be in 330 yuan/gram. If the jewelry you buy weighs 10 g, then the jewelry price is equal to 330* 10=3300 yuan. Then different kinds of jewelry will add some labor costs, generally between 50- 150 yuan, and then 3300 plus this labor cost is the final price of jewelry!
