Most people who buy precious stones in their country of origin will be cheated. Many consumers who don't know about precious stones and have no relevant knowledge and experience think it will be cheaper to buy precious stones in the country of origin. As a result, there are many news of being cheated every year. There are also many people who will say that jewelers not only get goods from the origin of gems, but also have not been cheated, so the probability of buying gems from the origin of gems is not great, which is a wrong cognition. Gem is a very precious and non-renewable mineral resource. As an ordinary consumer, there is no chance to get in touch with the primary source of precious stones. Unless there is a channel, they can only buy it in the local jewelry retail store or market. Without professional knowledge and experience, they are very easy to be deceived. Many consumers also know that the authenticity and quality of gems can be judged by certificates, but there are many places where certificates are not authoritative at all, and it is common to be fooled if you don't know enough. Therefore, buying as few gems as possible in the origin of gems is very likely to be cheated, and it is not necessarily cheap. It is also a big problem to find that you have been cheated to protect your rights.
