Looking for the true colors of these stones. "What stone is it?" "How is it formed?" "Did it move to the beach artificially?" Location: A hotel beach in the tropical area.

This is a volcanic rock found in the tropics. Some are carried naturally, and some are carried artificially. Don't worry about this.

Volcanic rock (commonly known as pumice or porous basalt) is a functional environmental protection material. It is a very precious porous stone formed by volcanic glass, minerals and bubbles after volcanic eruption. Volcanic rocks contain dozens of minerals and trace elements such as sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and molybdenum. It has far-infrared magnetic waves and no radiation. After the ruthless volcanic eruption, after tens of thousands of years, its application fields have now expanded to the fields of architecture, water conservancy, grinding, filter materials, barbecue charcoal, landscaping, soilless culture, ornamental products and so on, and it plays an irreplaceable role in all walks of life.
