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.
