diamondhead

Diamondhead refers to a distinctive geological formation found in various locations around the world. These formations are characterized by their sharp, pointed peaks that resemble a diamond. The specific geological processes that create diamondheads vary, but they often involve volcanic activity, erosion, or the uplift of rock strata. One well-known example is Diamond Head Crater, a tuff cone on the island of Oahu in Hawaii, which is a popular hiking destination and offers panoramic views of Waikiki and the Pacific Ocean. The name "Diamond Head" was given by British sailors in the 19th century who mistook calcite crystals found on the slopes for diamonds. In other contexts, "diamondhead" might describe a specific type of crystal habit or a sharp, angular feature on an object. The term is generally used to denote a prominent, pointed landform or feature.
