Myrickite is a local name used for a form of chalcedony with red inclusions of cinnabar.[1] It has a Mohs hardness of 7. Although similar in color, this material should not be confused with the stone from China referred to as "Chicken Blood", as that material is a cinnabar stained serpentine with a hardness of 2.5-4.[citation needed] Unique to the United States, Myrickite is found at only one location in any quantity.[citation needed] During the early 1950s,[citation needed] Myrickite had been found in small quantities at the Manhattan Mine,[2] located in Napa County, California, United States.
