Pearl symbolizes health, tranquility, and wealth in people's minds, and is listed as a lucky stone for June's birthday in the international gemstone industry. Pearl is very beautiful, but behind its beautiful appearance, there is a touching story. In fact, the process of pearl formation is very painful. Under the vast sea bottom, there are clams living, and each clam's body will enter a grain of sand. The clams have to endure the pain of grinding and grinding the sand every day, and in the end, they will grind the sand into a bright pearl. So now the moving pearls in our eyes are actually transformed from ordinary sand particles. Pearl has always been considered a gift from the gods to the earth. In fact, apart from the explanation given by the above divine grace, it is hard to believe that an ordinary oyster can breed a perfect treasure.
