Possibly the best example of these minerals from a one time find in 2003. To my eye this was clearly the most esthetic piece . Doyleite is a quite rare mineral and Gibbsite is also not very common and never as attractive as this . Good fluoresence too, this piece has an x ray certificate to go with it. Without such proof the Doyleite is impossible to certify as being present in the specimen as it looks much like Gibbsite. Great overall esthetics, form and color for the species!
