Guimaraesite is a newly described complex calcium/zinc/magnesium/iron beryllium phosphate, which comes from an unnamed pegmatite working in this valley. This specimen is a complete floater quartz cluster the size of a large grapefruit, with exception only of one small bit on one side which is contacted. It is smothered on one side by Guimaraesite in sub-mm spherical crystal clusters. This is the first rich specimen I have seen. Described in 2006.
