Barite Inclusions in Fluorite - GIA

inclusion with respect to the color zoning of the flu-orite host. The base of the inclusion rested in a zone of brownish yellow fluorite that comprised the entire pavilion of the stone, giving the fluorite a brownish yellow color face up (again, see figure 2). The upper portion of the inclusion was enclosed in a fluorite color layer that showed a strong purple-to-blue color change.

Form Color What is Fluorite?

Fluorite can also be colored by inclusions which scatter and/or absorb light. The most common kind of inclusion in fluorite are microscopic beads of petroleum that scatter light. This type of inclusion is common in fluorite from sedimentary and Mississippi Valley type (MVT) occurrences such as those near Cave-In-Rock, Illinois, and Elmwood, Tennessee, and creates shades of purple, yellow, and blue.
