HYDROXYLHERDERITE Palermo Mine, N. Groton, NH Approximate 1 mm field of view. Blocky, yellow-brown, hydroxylherderite crystals on beryllonite.	Species: HYDROXYLHERDERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: Approximate 1 mm field of view. Blocky, yellow-brown, hydroxylherderite crystals on beryllonite. Field Collected: Walter Lane Catalog No.: u1263 Notes: The hydroxylherderite identification is a visual one. Beryllonite, etched beryl, brazilianite, vivianite, and sphalerite are also on this specimen, u1263. Per Bob Whitmore's Palermo book, hydroxylherderite (a beryllium mineral) is sometimes associated with beryllonite, as on this specimen.

Carpet of iron oxide stained Hydroxylherderite crystals. Field Collected: Dana Jewell Catalog No.: u1361 Notes: Full specimen view is a natural sunlight photo.
HYDROXYLHERDERITE Parker Mtn. Mine, Center Strafford, NH 0.9 mm clear hydroxylherderite crystal on quartz crystal	Species: HYDROXYLHERDERITE CaBe(PO₄)(OH) Locality: Parker Mtn. Mine, Center Strafford, NH Specimen Size: 0.9 mm clear hydroxylherderite crystal on quartz crystal Field Collected: Bob Janules Catalog No.: A Bob Janules specimen Notes: Identification by Bob Janules
HYDROXYLHERDERITE Parker Mtn. Mine, Center Strafford, NH 4.5 cm specimen with 2.3 cm hydroxylherderite crystal	Species: HYDROXYLHERDERITE Locality: Parker Mtn. Mine, Center Strafford, NH Specimen Size: 4.5 cm specimen with 2.3 cm hydroxylherderite crystal Field Collected: Neil Santerre Catalog No.: A Neil Santerre specimen Notes: Cookeite, bertrandite and apatite are also present on this specimen. This specimen ranks among the very best from the Parker Mtn. Mine.
HYDROXYLHERDERITE Palermo Mine, N. Groton, NH 1.1 mm hydroxylherderite crystal	Species: HYDROXYLHERDERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1.1 mm hydroxylherderite crystal Field Collected: Forrest Fogg Catalog No.: u1760 Notes: The crystal termination is a group of small pyramids.
HYDROXYLHERDERITE Palermo Mine, N. Groton, NH 6 mm field of view	Species: HYDROXYLHERDERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 6 mm field of view Field Collected: Walter Lane material Catalog No.: u1605 Notes: My visual ID for these balls was crandallite. A polished grain EDS analysis suggested just a simple calcium phosphate such as apatite. A fluorine response (@ 677 eV, above the 525 eV oxygen peak) is totally absent in the EDS spectrum indicating these balls cannot be fluorapatite. These balls are an excellent comparative match for a similar occurrence of hydroxylherderite at the Dunton Mine in Newery, ME. The EDS detector cannot detect beryllium. The detector response to apatite-(CaOH) and hydroxylherderite are very similar. Several knowledgeable collectors who have looked at this specimen agree that the spheres are most likely hydroxylherderite. Tabular apatite crystals are also present in this view.
