Phosphorescence (in the common sense of the term) observable with the naked eye:

No data

Comments:

Pectolite and wollastonite from Franklin, New Jersey, USA, have the same luminescent color but the association with hardystonite is typical of clinohedrite.

Clinohedrite occurs sometime as an alteration of purple fluorescent hardystonite (see http://www.mindat.org/photo-263085.html)

Activator(s) and spectrum:

Activator(s): Mn²⁺ ,

Comments on spectrum and activators:

Activator is Mn²⁺ substituting to Ca²⁺;

Best localities for fluorescence (*):

• Parker Shaft, Franklin, Franklin Mining District, Sussex Co., New Jersey, USA;

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
