JEWELRY, UNIQUE GIFTS

Dichromate refers to the photosensitive material (sandwiched between two plates of sealed glass) used to record these holograms. 

Because  dichromate holograms are easily viewed, they were used for a wide range of artistic, decorative and promotional applications.  Production peaked in the late 1980s when thousands were used as watchfaces and jewelry items.
