Sharp lustrous opaque crystal of grossular 1.0 cm across set nicely on matrix. In good condition. Nice thumbnail for this famous locality.

The Pitts-Tenney Quarry in Minot, Androscoggin County, Maine, is a notable geological locality famous for its calc-silicate skarn deposits that feature large, lustrous brown grossular garnet crystals embedded within a diopside matrix. Historically operated as a small quarry and later celebrated as a premier mineral collecting site, it has attracted rockhounds and museum curators for decades due to the exceptional size and clarity of its garnet specimens. However, growing residential encroachment has significantly restricted heavy collecting and modern access to the site.
