About the product: Origin of Taiwan Sapphire Taiwan sapphire was first discovered by the Japanese inadvertently when mining ore in Taiwan, and it was named because of its bright color and rareness, and it was only available in Taiwan at that time. So far, "Taiwan Sapphire" has become a business name. Therefore, many people mistakenly think that "Taiwan Sapphire" = "Sapphire" made in Taiwan. In fact, this is not correct! There is another saying on the market that the better quality is Taiwan sapphire, and the Bronze quality is Bronze sapphire. The quality of the marrow is different, not necessarily the best ones are made in Taiwan! Therefore, consumers do not have to be obsessed with the place of origin.
