These arsenopyrites have just the COOLEST crystal form! They are perfect rectangular columns, some blocky, others elongated. The profusion of arsenopyrites from China has dulled the appreciation of specimens from other localities, but this specimen is desirable for its locality and rare crystal form. From the collection of noted California collector Charles Hansen.
