This GEM Pulsifer apatite is one of those things you have to see in person to understand why they are still so legendary, 60 years or so after they were found in the 1960s in the "glory hole" pocket of this famous old mine in Maine. They simply GLOW in a showcase and leap out for a neon intense color that is unequaled in the mineral world. Although small, this is a superb, stunning specimen that obviously takes a good photo. There was a feature article in the 1960s Lapidary Journal, and also in Peter Bancroft's book, Gem & Crystal Treasures (1984). Every major thumbnail collection has had a Pulsifer in its core suite, that I can recall, as this is one of the rarest items you can own, as a collector of USA thumbnails.
