Standout aquamarine spots in Maine

Hand-picked from the full list below, with the reason each one earns a trip.

Mount Apatite
Androscoggin County County
Mount Apatite is a lithium-rich pegmatite district where the Pulsifer Quarry produced some of the finest purple apatite crystals in the world, alongside green and pink tourmaline, aquamarine, and lilac lepidolite. The historic feldspar quarries now sit inside Auburn city parkland, making this one of the few Maine gem localities with genuine free public access. Garnet and smoky quartz turn up in the same dumps.
Edgecomb Quarry (Schmid Preserve)
Lincoln County County
The Edgecomb pegmatite pits sit inside the 766-acre Schmid Preserve, town land laced with more than seven miles of public trails, where 1880s feldspar and mica workings exposed almandine garnet, beryl, and aquamarine. The preserve is free and open to the public. Smoky quartz and muscovite occur in the same pegmatite.
