The first thing is to buy solid, because the quality of solid is better. It will not be as fragile and deformable as a hollow one. If you are rude, it will be crooked and flat with a little knock. A solid one will be more stable, so you don't have to be careful everywhere. Also, don't buy some fancy styles, the beads are basically hollow. Don't touch those hollowed-out models that you must regret buying. Those are superficial, and the actual shape is easy to collapse.
Don't listen too much to the shop assistant. They usually sell fancy gold jewelry with exquisite styles, but they are not durable. In this way, if you wear it for a while and the inside collapses or gets dirty, you will definitely come back to the gold shop for cleaning or reprocessing. This will earn more maintenance fees. Or you don't like it and want to trade it in. Those hollow holes look beautiful, and the actual depreciation is not as good as those solid ones.
In recent years, it is also very popular to wear 18k necklaces and jewelry such as rose gold and platinum. Because pure gold jewelry is softer and easier to wear than K gold. K gold and the like will be hard and will not be deformed by the addition of other metals. Nowadays, many jadeite gems are inlaid with rose gold or platinum. It doesn't matter if you just buy it yourself. If you want to buy value-added products, you'd better buy pure gold.
