A galena crystal on matrix, from pre-1967 workings in the Tri-State district. There are interesting cubic growths on the corners of tha main crystal.
These are not to be confused with the contemporary Viburnum Trend, Missouri specimens. Although part of Missouri was included in the Tristate district, those workings were on the western side of the state. The more recent production comes from the eastern side. Personally, I like these old examples better-- although the lusters are usually duller, they tend to have a sharper, more geometric appearance than the Viburnum specimens, with their messy compound faces. The chert matrix is also somewhat cleaner in appearance than the breccia (?) that is found with the Viburnum examples.
