Fluorocannilloite has only been identified once from Pargas, Finland and then only as graygreen grains in marble. Although three grains were used to determine the optical properties of the mineral, the mineral was described from a single x x mm grain. Any new specimen should at least be supported by an EMPA also including F measurements.
