1. Low production cost: Xinjin Jewelry is a company that mainly produces small ornaments. Compared with large-scale gold and silver jewelry enterprises, its production cost is lower, so the product price is more close to the people.

2. Low brand awareness: Compared with well-known brands such as Chow Tai Fook, Luk Fook and Zhou Shengsheng, Xinjin Jewelry has low brand awareness, so it is impossible to raise the product price through brand premium.

3. Insufficient marketing and publicity: Xinjin Jewelry may not invest enough money in product marketing and publicity, which will also lead to lower product prices.

4. Affected by market conditions: The price of gold may fluctuate due to market conditions, so in some cases, the price of new gold jewelry products may be relatively low.

To sum up, the product price of Xinjin Jewelry is relatively low, which may be related to its production cost, brand awareness, marketing promotion, market conditions and other factors.
