1. Price factor: Russian Zijin is usually expensive, especially in some boutiques or counters, and its price may exceed the budget of some consumers. For consumers with limited budgets, buying Russian Zijin may bring greater economic pressure.

2. Uncertainty of investment return: Although Russian Zijin has certain investment potential, its price is affected by many factors such as market supply and demand and international political situation. This makes its investment return uncertain, and investors need to take higher risks.

3. It's hard to tell whether it's true or false: Because Russian Zijin is scarce in the market, some unscrupulous merchants may sell fake and inferior products. For ordinary consumers, it may be difficult to identify the authenticity, which also increases the risk of buying.

4. Style and preference: Everyone has different aesthetic and style preferences, and some people may prefer other types of jewelry or metal ornaments to Russian Zijin. Therefore, from the perspective of personal preference and style, it may not be necessary to buy Russian Zijin.
