Brilliant black sand at Punaluu Beach, Hawaii. If you plan to go to the Big Island of Hawaii I'm your "go to guy" for all of your Hawaii needs. I went to college at the University of Hawaii and have a vacation home just a short drive from Punaluu.
Diamond Head, Oahu, Hawaii is the name of a volcanic tuff cone on the Hawaiian island of O'ahu. Its English name was given by British sailors in the century, who mistook calcite crystals on the adjacent beach for diamonds. Hawaii is the state.
