This is one of the larger Palermoite crystals that I have seen personally. The original label from "The Thurston's" stated only Fluorapatite, but there are numerous Palermoite crystals as well with the largest at the arrow at 5mm. All of the other crystals are 1mm or so. The Fluorapatite are tabular white to light lavender.
