Granite pegmatite. Grafton field. Hosted by muscovite-sillimanite-staurolite schist. Located on Isinglass Mountain. First commercial mica quarry in U.S. (often cited as 1803, but published records seem to suggest a few years later than that date). Mined for feldspar beginning in 1912, and later for beryl as well. feldspar mining was intermittent and was active in the mid-1960s, ending by about 1969.
Noted for its excellent vista views and steep dumps with tunnels and galleries into the granite pegmatite. Collecting is permitted after paying a fee ($25 per adult in 2011).
The earliest discovery of the famous gummite specimens from this locality was announced by Benjamin Shaub in 1936: "Recent work in mining for feldspar at the Ruggles' pegmatite has exposed numerous uranium-bearing ... minerals." The very first specimens were apparently collected by Ray and Alvin Schortmann who lived not far from Ben Shaub in Northampton, MA (B. Shaub, pers. comm., 1989). The abundance of gummite was one of the factors which influenced the Schortmann brothers to start a mineral business, beginning about 1938, that lasted for about 25 years.
As of June 2022, the property was listed for sale.

| ⓘ Anglesite Formula: PbSO4 Description: Small, well-formed crystals were found in partially altered galena (Bjareby, 1965). |
| ⓘ Autunite Formula: Ca(UO2)2(PO4)2 · 10-12H2O References: |
| ⓘ Formula: Ca(UO2)6O4(OH)6 · 8H2O Description: No data or specimens known. |

| ⓘ Bornite ? Formula: Cu5FeS4 |
| ⓘ Formula: CaCO3 |
| ⓘ Chrysoberyl Formula: BeAl2O4 References: Meyers, T. R., Stewart, Glenn W. (1956) The Geology of New Hampshire Vol. 3 - Part III - Minerals and Mines. The New Hampshire State Planning and Development Commission, Concord, NH. p.19 |
| ⓘ Formula: (Na,Ca,Pb)(UO2)O(OH) · 0-1H2O Description: Frondel (1956) noted: "Clarkeite has been said to occur in reddish-brown gummite at the Ruggles pegmatite, Grafton Center, New Hampshire, but it was not observed in specimens from this locality examined in the present study." As gummite and other minerals were frequently reported from this and other localities without data, frequently as wishful thinking, the clarkeite folklore is unbelievable given the thoroughness of Frondel's uranium mineral research. |
| ⓘ Coconinoite ? Formula: Fe3+2Al2(UO2)2(PO4)4(SO4)(OH)2 · 20H2O Description: There is a large degree of uncertainty about the locality in NH for this species. Only PRIMARY reference is Young, E., Weeks, A., and Meyrowitz,R., 1966, Coconinoite, A New Uranium Mineral from Utah and Arizona, Am Min v 51:651-663 which states of the species: "... two from unknown localities, one from Wyoming, and one from New Hampshire, which is certainly in a different geologic environment..." The specimen is not elsewhere mentioned or described. There has been a strong folklore belief that the coconinoite mentioned was from the Ruggles Pegmatite because so many uranium minerals were found there and, at one time, were abundant. No subsequent discoveries of New Hampshire coconinoite have been made and the original reference specimen is lost. |
