This small hand specimen appears to consist of part of a radiating spray of highly compact Zinnwaldite blades. These blades appear to reach lengths of 1.5" (0.8 cm) and are impossible to define as individuals due to their intensely compact nature. The material strongly resembles all micas in its flaky habit and pearly luster. There is no host rock present.
