Re: Re: Bisbee specimen

Hi Greg,

You appear to have some fluorite, malachite, malachite with cuprite, chrysocolla, and possibly some gem silica. The focus is rather soft to blurry in most of the pictures, making ID somewhat tenuous at best.

What is the resolution of your camera? If it lacks a macro focus mode, you might get more serviceable pictures by backing away from the subject until you can get a sharp focus, then crop away the extraneous background.

How did you come by the collection? When you say a "Bisbee collection" do you mean a collection of rocks all purported to be from Bisbee, AZ localities? Or a collection assembled by someone who lived in Bisbee, a collection acquired in Bisbee, or?
