Myrickite
Myrickite is a name used for both the agatized and opalized
Manhattan Mine,[1] located in Napa County, California
, United States.
The name "Myrickite" is a lapidary term like "Montana Agate" or "Thunder Egg", not a mineral name. In addition, the percentage of mercury (0.01%) in this material is enough to give Myrickite its beautiful coloring. Myrickite is named after Francis Marion "Shady" Myrick who discovered it while prospecting in California's Death Valley in 1911.[2]
