An Azurite/Malachite specimen with Azurite on one side and Malachite on the other. The Azurite is a deep blue and drusy with crystals less than 1mm. It glistens in your hand. The other side contains gorgeous balls of pastel green Malachite to 3mm. Overall it is very attractive. Waidler worked at this mine and self-collected this material. It is likely the best to have surfaced from the mine and should be cherished by any AZ collector.
