This is another rare mineral from the rare mineral district of the Khibiny mountains, Kola Peninsula, Russia. It is found as small grains to about 1mm associated with potassium feldspar, nepheline, sodalite, aegirine (main rock-forming minerals), plus pectolite, astrophyllite, barytolamprophyllite, shcherbakovite, vuonnemite, kazakovite, ershovite, chkalovite, natrite, villiaumite, and rasvumite. The name is for Scottish chemist A. Crawford (1748- 1795), who discovered the Sr salts. Type material is at the Fersman Mineralogical Museum, Moscow, Russia
Crawfordite fluoresces bright yellowish green, band not stated.

In his book, Jack de Ment spoke about crawfordite as a form of chalcedony from Barstow, California, fluorescing in green under SW;
