Benitoite and Neptunite
We have been cleaning material from the Dallas Gem Mine in San Benito County, California which were collected over 10 years ago. This is the first of several lots, and mainly consists of Neptunites and low-end Benitoites (mainly for fluorescent specimens.) We will have more to come as we continue prepping them. Enjoy.
