This is a new IMA mineral recently approved. Tapiaite forms tiny clear lath-like crystals less than 0.03mm in size. Impossible to capture with my photo set-up, these crystals can nonetheless be seen in the photos as all the hundreds or thousands of reflections all over most of the matrix. It is associated with light bluish green Joteite. This is a fabulous, rich specimen. I have a few more of these if you miss out, just let me know. This is the best one.

This is a nice cluster of light translucent green tabular Tavorite crystals. The cluster measures about 1mm but contains dozens of individual well-defined crystals. Typically Tavorite at the Tip Top is light green and granular looking with sugary habit. Tavorite crystals such as these are rare - from anywhere. It is a relatively rare lithium phosphate found exclusively in granitic pegmatites. The matrix of this specimen is mostly compact fibrous black Rockbridgeite.

Larger specimen of pinkish red Hureaulite in masses and crystals to 3mm with cavities filled with sugary lime green Tavorite and clusters of well-defined, excellent crystals in groups to 2mm. These are fabulous crystals of Tavorite, some of the best around. At the Tip Top mine, Tavorite is uncommon and crystals are very rare. I'm not sure if there is a better locality. Scattered around the cavaties to a lessor degree are tiny less than 1mm opaque yellow-orange Ushkovite crystals, deep red Bermanite and purple Leucophosphate crystals.
