The 800-dollar white gold and silver necklace is not real. Platinum is a precious metal, while silver is a relatively cheap metal. The price of platinum is much higher than that of silver, and a platinum necklace with 800 yuan price is not available. In addition, platinum necklaces are generally made of pure platinum or alloy platinum instead of silver plating.

Be vigilant when buying jewelry, especially expensive necklaces, choose formal channels to ensure that you get certificates or qualified appraisal reports. This can ensure the quality and authenticity of the purchased jewelry.

When buying jewelry, besides the price factor, we also need to consider factors such as brand reputation, material identification and craft level. If the price of a commodity is much lower than the market price, it is likely to have quality problems or fake and shoddy products. Therefore, we should choose rationally and avoid being cheated because of low prices.

In a word, the 800-piece platinum-covered silver necklace is probably untrue. You need to be cautious when buying jewelry, and choose reliable channels to buy it.
