First of all, although the price of gems in Sri Lanka is relatively low, the gems themselves are not expensive. Therefore, in theory, gem, as a commodity itself, does not have much profit space. This enables some unscrupulous merchants to sell fake and inferior products to obtain higher profits.
Secondly, Taobao platform has a large number of sellers, a wide variety of goods, and it is difficult to supervise. Although Taobao platform has a corresponding complaint and rights protection mechanism, in this case, consumers may have to bear the risk of identifying the authenticity of gems.
Therefore, if you want to buy Sri Lankan gems, you'd better choose a reputable merchant or a professional jewelry store to ensure the authenticity and quality of the goods. In addition, it is best to know some basic knowledge of gem identification before buying, so as not to be deceived by unscrupulous merchants.
