Wavellite with Pyrrhotite Demantoid The Monazites are some of

The Monazites are some of the most distinct and impressive twinned crystals I have seen from Bolivia and they actually perform a color change in different lighting ranging from orange-pink to a white/yellow depending upon the light source

Specimen # BOL711B149

This twin is a great example of the material as it shows a fairly “open” twin

This piece is remarkable for Bolivia as it features a type of crystallization that is virtually unheard of for this country

I honestly believe that the layer of oxidation and dirt that covered the piece actually helped to preserve the quality of the twin

Wavellite with Pyrrhotite Demantoid The Monazites are some ofAlthough Wavellite is a fairly well known phosphate species, it is truly only found in a handful of localities in well crystallized display specimens. The majority of the Wavellites from world localities feature either micro crystals, or incomplete (broken) spheres on matrix. The Bolivian Wavellites, particularly those from the famous Siglo XX mine, are among the best in the world due to the fact that they occur with eye visible spheres that are often
