A sharp and complete crystal of the very rare "pseudocubic" habit Quartz, which is also very large for the form. The form is more correctly a skewed cube with overdeveloped rhombohedral faces that are not at 90 degrees but can look like it from several angles. No damage. This was incorrectly attributed to a small Arizona find but it is now confirmed as a very choice New Mexican specimen.
