Jewelry is a special commodity. As long as it is not a quality problem, it is generally non-refundable. Of course, you can negotiate with the merchants calmly. General merchants will change your favorite style for you. If it is a wedding diamond ring, the commemorative value is far greater than its actual value. After all, you can wear it for a lifetime as long as you don't lose it. Every time I see it, I will have good memories.
