Roserita is a very rare material.
In the early 1940’s Gold Prices spiked. As a result of the new high prices some Prospectors revisited the old gold mine areas in places such as Colorado, California, Alaska, etc.
These crusty codgers would build brick kilns over open pits and super-heat that gold-bearing ore that still litters the sites. The return was small and the practice only lasted about 5 years. The gold would sink to the bottom and the beautiful red gold slag would run off down the mountains, and solidify into boulders of Brilliant Red and Orange, much like Obsidian is formed in a volcanic reaction.
It is very rare, but we are lucky enough to have a nice collection. The material is durable and readily polishes to a beautiful shine. So far we have found no other information on it. We feel very blessed to have such a lovely earth element to work with. Roserita is the only material available in such a true red color. Some pieces have swirls of orange and these are even more rare.
Roserita was named after a beach in Mexico because of the brilliant color.
