Shanghai Gallery - Cases

In 2013, The Arkenstone opened a gallery in Shanghai, China. With the incredible economic growth occurring in Asia, we are excited about bringing these fine mineral specimens to China and introducing western-style mineral collections to their evolving tastes.

Both galleries are open to the public by appointment only, and we are always eager to share our love for fine mineral specimens with other enthusiastic friends! Contact us at for scheduling.
