Where is the small jewelry in Guangzhou? I am in Shenzhen now, can I tell in detail how to go? Thank you! There are high scores!

For example, wooden chopsticks are suitable for relocation and wedding gifts. Want the manufacturer!

I bought a AU750 diamond ring with a value of about 3K at 10.1 on Saturday. There are jewelry appraisal centers for appraisal certificates and invoices, but my wife brought about a week, so gold began to turn white. Is this fake? If it wasn't for the reason? how should I solve this?
