OK, this one boggled minds at Denver! It fooled me, and it fooled numerous people...nobod guessed BLUE ALBITE CRYSTALS! The identity was finally settled by analysis at U of AZ. It seems to be a one-opff. I have seen no others of this material while waiting for this one to be cleaned and returned to me, and I think its a very important rarity in that it is an extremely impressive (unprecedented?) example of an extremely common and usually boring species. The major crystals reach 5 x 4 cm in size and the slender, most finely formed crystal in the middle is about 3.5 cm tall, very 3-dimensional. Besides, its pretty! I admit I would normally be the last person in the world to say an albite is a world class crystallized mineral specimen, but then that is the fun of the hobby...you never know what will come out!
