Oregonite is a mineral specimen that has become synonymous with the state for which it is named. However, there are a few alternative names that have been used to describe the mineral in earlier literature. One such name is "Portland rock," which likely refers to the city of Portland in Oregon. Another name given to the mineral is "Christmas rock," which may be a reference to the mineral's green and red coloring. Some have also referred to oregonite as "thunderegg," due to the mineral's spherical shape resembling a thunderbolt. Despite having a few different names, oregonite continues to be most commonly referred to by its original name.
