Yes, it's best to buy big brands. First, the quality is guaranteed. Although small brands are cheap, the handling fee will be more expensive when they are realized in the future.

Other considerations:

It is best to buy during large-scale activities, and shopping malls should also have corresponding preferential activities.

It is best to buy thousands of gold, which has better value preservation.

If you buy a necklace or bracelet, make sure that the connecting buckle is strong enough. Many cases have been lost, and there is something wrong with the interface.

Gold jewelry contains relatively high processing costs, generally 30-50 grams. If the purpose is pure investment, it is recommended to buy investment gold bars, which are sold in banks and gold shops, with better value preservation performance.

If you only invest in preserving value, you can also buy paper gold, which is cheaper and safer to keep.
