Mineral News was founded some twenty years ago and has developed a following of
avid mineral collectors seeking timely information about new finds and other items
of interest to the collector community. Articles are solicited from collector and scientific authors.

Dakota Matrix was founded in 1996 and has offered systematic and rare mineral specimens online since 1998.
