Mineralogy

Divisional Collections

The Division of Mineralogy oversees an historically important worldwide collection of approximately 35,000 specimens, most catalogued into a systematic collection created from the original Yale Peabody Museum holdings and the G. J. Brush Mineral Collection. There are 36 documented type specimens, and other presumed type specimens requiring further documentation.

In addition to the many referenced specimens, the collection contains suites of material from localities that no longer exist, early prospecting material, a collection of gemstones, and a sizeable collection of Connecticut minerals.

The largest and most important collection in the Division, approximately 15,000 specimens, is the G. J. Brush Mineral Collection. Other collections include:

Blum Collection of pseudomorphs
Lazard Cahn Collection of micromounts
