Does anyone out there know any history on when Finnish
Spectrolite was first discovered and made it’s way into jewelry?
I belong to the SCA, an organization that re-creates the Middle
Ages and Renaissance eras and have had a few discussions with
other jewellers in the SCA on this but no one seems to know when
it really appeared. Any help would be greatly appreciated as I
got some GORGEOUS rough at Tucson and would like to incorporate
it in some of my Medieval designs.
