Important Update News
The RRUFF Project is being updated to improve its interface and content. The beta version of the update is accessible to the public at RRUFF.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional. Existing RRUFF.info links will resolve to the new site after RRUFF.net is officially released.
We are grateful to NASA for the funding of this effort.

Name: Avogadrite RRUFF ID: R110062 Ideal Chemistry: KBF4 Locality: Mount Vesuvius, near Naples, Campania, Italy Source: James Shigley [view label] Owner: RRUFF Description: Colorless consolidated granular. Some of the material consists of transparent gemmy crystals. The unidentified associated yellow material is a thin coating, something like a bubble surface, that turns white under acetone. Status: The identification of this mineral has been confirmed by single-crystal X-ray diffraction. |
