South Dakota fluorescent fossil ammonites
The calcite will fluoresce from white to yellow to orange. The chalcedony usually shows up as a green fluorescence. Usually the stronger
fluorescence is under long wave and is the first photo shown in the fluorescents (South Dakota) section of the web site. Chalcedony
usually does not fluoresce well under long wave, but does fairly well for the fossils from this area.
Due to limitations of the web site software we are unable to show each of the minerals available under normal light, long wave ultraviolet
light, and short wave ultraviolet light. We will attempt to compensate for this short coming by providing a link to another page below which
will give you photographs of similar specimens under the three lighting conditions.
We are limited to using only two photographs for the individual specimens being offered for sale. The first one you see will be the one
which offers the strongest fluorescence. Whether it is long or short wave will be indicated in the discussion of the specimen at the lowest
level (after you click on the image or the product name). If only one type of light will fluoresce the specimen or a second fluorescent image
is not available, then a photo of the specimen in normal light will be used at the lowest product level.
