Kazanjian history includes rare and unusual special stones such as chrysoberyl, cat's eye, Alexandrites, star sapphires, paraiba, demantoid garnets and opals.
Harry Kazanjian created the Mexican Opal market and opals became another trademark for the Kazanjian's. James and Stan visited mines located in a very remote location near Guadalajara and uncovered several luminous Mexican opal stones. A few years later in the late '50s, the Kazanjian's went on another hunt for more opals in Australia. They discovered the most magnificent collection of black opals that has ever been put together in the world to date. The curators of the Los Angeles Natural History Museum were so impressed with the collection that they begged to have the stones donated to their permanent collection.
