The ancient bracelet faded and can be repaired if it looks bad. Real ancient gold will not fade. You can buy ancient gold jewelry as long as you go to a regular and qualified jewelry store offline. There will be a situation that looks similar to fading, which may be caused by accidental contamination of chemicals containing lead and mercury during wearing. As long as you take the ticket to the jewelry store you bought at that time and burn it with a high-temperature musket, you can restore the original color.
