97idcets ((MARTINITE-WHITLOCKITE)), Philadelphia Academy of Science #22041, $10 MINIMUM BID, Palermo Quarry, North Groton, New Hampshire, 7.5 and 7 cm, 2 Cabinet | |
Here are two Philadelphia Academy of Natural Sciences specimens with a collection number of #22041. Old sheet of paper has a date of May 5, 1940. I checked mindat.org and Whitlockite is shown from Palermo and is white and resembles Albite. It is probably small crystals within the white areas of the specimens and especially on the larger specimen opposite the side I photographed before checking mindat.org . |
