Comments on spectrum and activators:
Luminescence probably due to uranium ions present in the chalcedony.
Best localities for fluorescence (*):
- Barstow, CA, USA (variety of chalcedony fluo green SW also called Siam agate or chapinite, a mixture of agate and jasper not the mineral crawfordite);
(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
