Fluorapatite     Neosla, Bash Valley, Balistan, Northern Areas, Pakistan.  This very large example is 9.3 x 6.4 x 4.5 cm.  It has large transparent regions and I initially purchased it to cut gems from.  I think it is better suited as a collector’s specimen.  It is a partial crystal with all its back regions being well healed.  It is a light yellow green color and has excellent luster.  One end is cleaved off but it is still attractive as a specimen.  Many good sized gems could be harvested from this if one so desired.  $200
