Thank you again Dr.Roger Weller of Cochise college,geology department.For once again putting the mineral with the tag this was in a box that was simply marked "blue minerals" it contained Azurite,Krohnkite,Turquoise and variscite.Not one of the minerals was the tag still attached they were amongst the news paper the rocks where wrapped in or on the bottom of the boxes.And as it turns out i listed this as the wrong mineral and Dr.Weller,was able to help me in correcting this.The tag simple said turquoise mountain,cali.This example is from an old collection that has been boxed up since 1975 until recently.And by the wording on the tag it was one grandma got herself as she did with many in her collection.She traveled the world being a professor in native american and eastern culturs.Re-attatched tag fragments can be scene.overall size is 3.5 x 3.0 x 2.3 cm.Gordon c De'Young collection.
