The iconic silhouette of Diamond Head State Monument sits along the Honolulu skyline just beyond Waikiki. This 760-foot tuff crater is one of Hawaii's most famous landmarks. Known as Leahi (brow of the ahi, or tuna) in Hawaiian, the crater was named Diamond Head by 19th century British sailors who thought they discovered diamonds on the crater's slopes. These "diamonds" were actually shiny calcite crystals that had no value. Formed more than 100,000 years ago, the crater was used as a strategic military lookout beginning in the early 1900s. Today, Diamond Head is a popular hiking destination with panoramic views of Waikiki and Oahu's south shore and has military and civil defense infrastructure that is still in use. Made in USA. Assembled in Mexico. Magnet measures approximately 5 inches by 2 inches.
