Kustos: About US
Kustos ("Means Curation")

Kustos is a consulting, appraising, and mineral and gem sales business owned and managed by John S. White. The principal objective of Kustos is to provide advice and guidance to mineral and gem museums, and to private collectors of minerals, gems and lapidary art.

Mr. White has been a consultant in this field since retiring from the Smithsonian Institution in 1991, where he was the curator-in-charge of the National Mineral and Gem Collection of the U. S. National Museum of Natural History.
