Rocks from George Campbell's Collection | This tiny little aragonite cluster from Serfou, Morocco is a great example of aragonite's habit of forming pseudo-hexagonal trillings. | | Ettringite is an uncommon mineral. This specimen comes from the N'Chwaning Mine, Black Rock, South Africa. |
| | From Searles Lake in San Bernadino County, this Hanksite specimen is representative of this dry lake mineral. It absorbs moisture from the air and must be coated with mineral oil. |
| | Related to the zeolites, but without the aluminum, Inesite is rather rare. This specimen comes from the Hale Creek Mine in Trinity Co., California. |
| | Among the many zeolite minerals from the Poona, India area, this fluffy Okenite cluster is surrounded by Gyrolite. It's one of my favorites. |
| | Pyrophyllite, soft as talc, is normally white and boring. This golden-colored specimen with an almost metallic luster comes from an unknown location in California. |
| | Rosasite, in this case coated with calcite, is one of the prettiest copper minerals I know of. This specimen hails from the San Xavier West Mine, in Pima County, Arizona. |
| | A specimen of Rutilated Quartz belongs in every collection, and always attracts attention. This one comes from Ibitiara, Bahia, Brazil. |
| | Stilbite's sheaf-of-wheat habit is easy to see in this specimen from Poona, India. |
| | Everyone has tourmaline, but I really like this tiny little green crystal poking out of its bed of mica. |
| | The Yukon Territory in Canada is the source for this beautiful specimen of Wardite. |
| | Wulfenite is a favorite in everyone's collection, and a specimen like this one from the classic Los Lamentos mine in Chihuahua, Mexico really perks up my display cabinet. |
