These are some of the largest Fairfieldite crystals I have come across - they measure up to 7mm. The Fluorapatite is a bonus, which is up to 7mm but mostly concealed. Excellent specimen.

This is a verified Fairfieldite by Raman, XRD, and EDS. The Fairfieldite occurs on dark olive green Roscherite as white disc-shaped crystals which are sometimes stacked but mostly as singular crystals. The color is a murky white. The size of the Fairfieldite crystals are about 0.3mm. Little white pearly cottonball-like crystal groups of Englishite are rare on the specimen and occurs on a reddish brown Roscherite. The matrix is Beryl. The Roscherite, Fairfieldite and Englishite occur along fracture fillings in the Beryl.
