Bertrandite was named after Leon Bertrand, a French mineralogist, and is one of the more important ores of beryllium, second only to beryl. Bertrandite is closely tied to the gemstone mineral beryl in many ways besides its use as an ore for the same metal. The two are often associated together as bertrandite is an alteration product of beryl.
