ALMANDINE Pond Hill (Pearl Lake Locale), Lisbon, NH Larger crystal is 1.7 cm	Species: ALMANDINE Locality: Pond Hill (Pearl Lake Locale), Lisbon, NH Specimen Size: Larger crystal is 1.7 cm Field Collected: Ron Lippard Catalog No.: 1282 Notes:
ALMANDINE Gilsum-Alstead pegmatite district, NH A 6 inch specimen, (BIG!)	Species: ALMANDINE Locality: Gilsum-Alstead pegmatite district, NH Specimen Size: A 6 inch specimen, (BIG!) Field Collected: Francis Maloney Catalog No.: Notes: A Gilsum Historical Society Specimen. Francis Maloney was the founder of the Gilsum Rock Swap and the postmaster of Gilsum, NH for many years. He reportedly owned several mines in the Gilsum-Alstead area and had a modest sized collection of specimens from area pegmatite localities.
ALMANDINE Gilsum-Alstead pegmatite district, NH A 3.5 inch specimen.	Species: ALMANDINE Locality: Gilsum-Alstead pegmatite district, NH Specimen Size: A 3.5 inch specimen. Field Collected: Francis Maloney Catalog No.: Notes: A Gilsum Historical Society Specimen.
ALMANDINE Murphy Prospect, Springfield, NH 3.2 cm crystal	Species: ALMANDINE Locality: Murphy Prospect, Springfield, NH Specimen Size: 3.2 cm crystal. Field Collected: Tom Mortimer Catalog No.: 1160 Notes: During a revisit to the "Murphy Prospect" in Sept., 2011, none of these garnets could be found. Recent information has indicated that there are two "Murphy Prospects" above the Globe Mine in Springfield.
ALMANDINE Murphy Prospect, Springfield, NH 2 cm crystal	Species: ALMANDINE Locality: Murphy Prospect, Springfield, NH Specimen Size: 2 cm crystal. Field Collected: Tom Mortimer Catalog No.: 1193 Notes:
ALMANDINE - Mn rich Joe Hill area, Springfield, NH 3 cm specimen with broken garnet section	Species: ALMANDINE - Mn rich Locality: Joe Hill area, Springfield, NH Specimen Size: 3 cm specimen with broken garnet section. Field Collected: Tom Mortimer - April 2005 Catalog No.: 1702 Notes: Certainly, a poor garnet specimen, but the locality is of interest to NH collectors. Phillip Morrill, in his Mines and Mineral Localities of New Hampshire booklet states: "the Joe Hill farm may be where all collectors got their spessartites." The earliest report of a Springfield, NH spessartine occurrence is in Jackson's 1844 Geology and Mineralogy of the State of New Hampshire, pg. 183. Jackson states: "A most abundant supply of perfect crystals of this mineral [spessartine] may be obtained in a few hours, by breaking up the mica slate rocks of Springfield, NH. They occur in such profusion that the mica serves only to connect them together, so that on breaking the rock with the hands they fall out and are found to be perfect crystals. They are of perfect uniform sizes and about as large as a filbert. Rarely two crystals are united together. They possess a good color, but none of them appeared sufficiently rich for jewelry, and I have not had them cut so as to try their effect. To the mineralogist and crystalographer, they are interesting specimens." Many NH field collectors, including myself, have searched the "Joe Hill farm" area looking for the spessartine occurrence. None I am aware of have found it. Nor have I seen a spessartine sample perported to be from this locality. This garnet specimen, collected from a pegmatite ledge in the Joe Hill farm area, was analyzed EDS analysis and determined have a modest manganese content, but the Mn content is less than the Fe content, so it belongs to the almandine species. End member formulae are: Almandine Fe²⁺₃Al₂[SiO₄]₃ Spessartine Mn²⁺₃Al₂[SiO₄]₃
ALMANDINE Gingras Farm Locality, Deering, NH 5.5 cm specimen	Species: ALMANDINE Locality: Gingras Farm Locality, Deering, NH Specimen Size: 5.5 cm specimen. Field Collected: Tom Mortimer Catalog No.: 1181 Notes:
ALMANDINE Un-named pegmatite, S. Uncanoonuc Mtn., Goffstown, NH 2.4 cm specimen	Species: ALMANDINE Locality: Un-named pegmatite, S. Uncanoonuc Mtn., Goffstown, NH Specimen Size: 2.4 cm specimen. Field Collected: Tom Mortimer Catalog No.: 900 Notes:
ALMANDINE - Mn rich Swain Brook pegmatite, Wentworth, NH 1.5 cm almandine crystal on feldspar matrix	Species: ALMANDINE - Mn rich Locality: Swain Brook pegmatite, Wentworth, NH Specimen Size: 1.5 cm (complete) almandine crystal on feldspar matrix. A smaller garnet is attached to the backside. Field Collected: Tom Mortimer Catalog No.: 782 Notes: This trapezohedral form is somewhat less common than the dodecahedral form. The pale color of this crystal hinted at a possibility it might be the spessartine species. An EDS analysis showed it to be a manganese rich almandine garnet. The Mn content is significant, but insufficient to classify this as spessartine.
ALMANDINE - Ca, Mn rich Soapstone Quarry, Richmond, NH 0.5 mm Almandine garnet	Species: ALMANDINE - Ca, Mn rich Locality: Soapstone Quarry, Richmond, NH Specimen Size: 0.5 mm Almandine garnet Field Collected: Tom Mortimer - 2013 Catalog No.: 1871 Notes: Mn, Ca rich almandine indicated by qualitative EDS analysis, (grain on carbon tape). Note that although the Ca response in the EDS plot is higher than the Fe response, the EDS detector response in the Fe, Mn region is substantially lower than in the Ca region. Taking this into account provides the basis for the determination that this garnet falls on the almandine side of the garnet species rather than the grossular side.
ALMANDINE with Staurolite Pearl Lake, Lisbon, NH 8 cm specimen	Species: ALMANDINE with Staurolite Locality: Pearl Lake, Lisbon, NH Specimen Size: 8 cm specimen Field Collected: Carlton Holt Catalog No.: A Carlton Holt specimen Notes:
