Introduction to beautiful stones: Crescent Bay Beach is a rare gravel beach in the country. Crystal clear stones are scattered on the beach, making it seem like a world of precious stones. Due to the movement of the earth's crust, the uplift of the landmark caused the rocks from the nearby mountains to fall off. The stones were left on the beach for a long time, and after being washed endlessly by the waves, they gradually turned into round pebbles. Because quartzite contains manganese, iron, zinc and other impurities, it appears in various colors and is very beautiful.
