If there is a clear word "thousands of gold" on the ring, it should be really thousands of gold. As for FQ, it is the brand of ring, not the abbreviation of thousands of gold. After wearing it for a week, the luster is still passable, which means you don't eat gold. If it fades a little, it's a little suspicious. If you don't have special contact with other metal parts, please take the receipt to the jewelry store for consultation and see what explanation they give you. The other jewelry store you spend is informal, but it is better. If there are quality problems, they will give you the best solution! I hope I can help you.
