What is the difference between beach pebbles and river pebbles?

These white stones are Milky Quartz crystals, (some call it Milk Diamond). Their white color is given to the rocks by inclusions of millions of tiny bubbles of water or gas that are trapped within the crystal, giving it its amazing milk-like color.
