There was also malachite in dark green, ropy flows and hemispheres coating cabinet-size pieces of matrix; fine examples of the now familiar Ojuela wulfenite and aurichalcite-included calcite; Milpillas mine azurite; 10-cm subparallel crests of white barite crystals on drusy amethyst (the first good barite from the amethyst fields of Las Vigas, Veracruz); spectacular Navidad mine, Durango creedite
and Cerro de Mercado, Durango fluorapatite specimens ...
Not by any means "new," but entirely distinctive and always dramatic, are the great spherical groups of transparent, colorless (but invariably brown-orange stained) creedite
crystals from the Navidad mine, Durango, Mexico.
Specimens showing gleaming sprays of colorless to amethystine creedite
crystals from the Potosi mine, West Camp, Santa Eulalia district, Chihuahua were first found in quantity around 1970, and the early 1980s saw several major finds, but the bounty ended in the mid-1980s.
At Prospector's Choice Minerals (call Ron Anderson in Littleton, CO at 303-790-9280), one could find lightly attached spheres of transparent, colorless crystals of creedite
from the Navidad mine, Durango, Mexico, in specimens measuring to 12 cm in diameter, for $50.
Collector's Edge (www.collectorsedge.com) also maintained a presence at Marty Zinn's hotel show, and in this room one could see specimens from a new discovery of creedite
made earlier this year in the Henderson mine, Clear Creek County, Colorado.
In a few of the specimens, carbonate-cyanotrichite is associated with cubic crystals of fluorite, which occurs in various colors at Qinglong; well-developed crystals of the uncommon species creedite
were discovered as well.

At least 120 mineral species have been reported, including fine specimens of calaverite, sylvanite, krennerite, melonite and creedite
Minerama (49 rue Republique, 42800 Rive-de-Gier, France), occupying the large booth to the right as you are facing the theater, had come up with some fine colored creedite
from Mina Navidad, Abasolo, Durango, Mexico.
However, about a year ago, in the old open pit, about 50 good specimens of pale purple creedite
were found--the first recorded occurrence of this species at Cripple Creek--and Dave Bunk had a half-casefull for sale at the Holiday Inn in Denver.
There was a load of fine green crystallized dioptase from Tsumeb, which caused this year to be labeled the "Year of the Dioptase." Excellent neptunite from California, choice anhydrite from Mexico as well as pink smithsonite, superb Los Lamentos wulfenites, rare Mexican creedite
and even rarer paradamite were available for a price.
From the mines of Santa Eulalia, Chihuahua, Mexico a rare mineral, creedite
, suddenly showed up.
