- I personally purchased these Sleeping Beauty Turquoise presentation cards at the Tucson Gem and Mineral show. These cards were among the last displayed items containing Sleeping Beauty Turquoise by the mine owners, when the mine was being shut down.
- These carded samples were bought directly from the miners, who assembled these cards.
- It was told to me by the miners of Sleeping Beauty Turquoise, that the black replaced the natural white matrix by tumbling the turquoise in a cement tumbler. This was performed at the mine site with black medium.
- This is a great obsolete souvenir from the original Sleeping Beauty mine, outside Globe, Arizona!
- The presentation card is the size of a business card, for sample size comparison.
