About Rock Currier’s Collection – India Specimens

Rock Currier was a remarkable person and highly influential force in the world of mineral collecting for many decades. Beginning in the early 1970s, he travelled the world in search of mineral specimens and he was a pioneering mineral dealer in many countries. He grew his mineral business while at the same time building an impressive personal mineral collection. Rock was also a manager of – and a prolific contributor to –, sharing his knowledge and expertise with the mineral community worldwide.

After Rock had begun his company (named Jewel Tunnel Imports, after the famous British railway “Jewel Tunnel” on the route from Mumbai to Pune, cutting through the zeolite “jewel” pockets), he travelled to India for mineral specimens. Over the years, he acquired and sold large volumes of Indian specimens, and he kept a few for his collection along the way.

Rock’s first trip to India was in 1972. The specimens in this update are just a few from Rock’s personal India collection and most date to the early years of his dealing in Indian minerals. Rock was a conscientious keeper of labels and information, such that all of his collection specimens were labeled with as much information as he had about them and they all bear catalogue numbers. Many also include a tiny label with the information affixed right to the specimen. Rock also wrote additionally about each specimen, and many typed specimen labels include this information.
