Named after Colonel Washington A. Roebling (1837 – 1926) , builder of the Brooklyn Bridge and avid mineral collector, donated collection to Smithsonian.

Roeblingite was reported by Penfield and Foote (1897) as nodular masses from the 1000 foot level of the Parker Mine in Franklin. Palache (1935) said that Frank Nason noted it near the contacts of marble and pegmatite. A subsequent report (Foote, 1898) was of roeblingite with lead from the 800 foot level.

About Us
We have been collecting amber in the field and prepping rough fossil amber specimens since 1993. Photographs of our specimens have appeared in National Geographic, Nature, Science, Scientific American, Discover, Time, Newsweek, The New York Times and others. We have been featured in PaleoWorld's The Amber Hunters. We offer authentic museum quality Dominican Amber display specimens of rare insects in amber and also authentic rare Dominican rough unprepared amber for sale. Our collections include museum quality rare insects in amber, unusual botanicals and flowers in amber and also rough unprepared Dominican Amber gemstones. We have traveled many times to the Dominican Republic where we have chiseled beautiful amber gemstones out of the lignite layers deep in the amber mines north of Santiago. We have excavated in the Palo Quemado and Los CaCaos blue amber mines and also in La Nueva Toca and the world famous La Toca amber mines way up in the mountains north of Santiago. For many years we have extensively collected mid Cretaceous New Jersey amber in the Raritan formation of central New Jersey and have traveled many times to collect late Cretaceous and early Paleocene amber in the Hanna formation of eastern Wyoming. We have collected mid Cretaceous amber in the Black Creek formation of eastern North Carolina and we have spent weeks collecting mid Cretaceous amber in the northern most Tundra of Alaska. Some of our most recent collecting trips have been in October of 2003 to the western Aleutian Islands some 1000 miles west of Anchorage to explore and collect Miocene amber, August of 2004 and April of 2006 we were back in the Dominican Republic to collect Miocene amber from the Palo Quemado amber mines which have recently closed due to the miners finding little amber, we were back to the Dominican Republic in April of 2006 to video in the La Toca amber mines, and in August of 2007 we excavated in La Toca and La Bucara. The La Toca amber mines had much water whereas on the other ridgeline the La Bucara amber mines were nearly dry! We collected much amber from both La Toca and La Bucara. In January 2010 we have collected at a new site of early Eocene amber in Asia. As these specimens are examined and prepared we will post some additional photos of this new locality. In June 2010 we collected Hell Creek Amber in the American Midwest..

We have donated many hundreds of amber specimens to museums in the United States and have several dozen new species of insects in amber named after us. We have examined several thousand specimens of rough Burmese amber and have prepped many new Burmese fossil amber specimens. We have traveled to Europe with colleagues to examine unusual spectacular Dominican Amber specimens in private collections and we consider the amber curators of the museums in Santo Domingo, Puerto Plata and New York City our friends. Exploring for and collecting amber along with the examination and research of amber is our passion.

Our amber comes direct from the Dominican Republic amber mines east of the world famous La Toca amber mine. These specimens do not go through any middle men, we acquire these specimens from the miners and mine owners directly at the amber mines.
