30 grams of ancient gold pendant, the production cost is more than 2000 yuan, which is a bit expensive. Generally speaking, there is no uniform standard for the cost of gold jewelry, and merchants will price it according to the complexity of jewelry technology. Moreover, the production process of ancient gold is complicated and the labor cost will be higher. However, the cost of more than 2,000 yuan is a bit too high relative to the price of gold itself. Therefore, we should carefully consider whether to buy this pendant.
