Phlogopite and Diopside from Franklin Marble, Sussex County, New Jersey, USA
Nice little micro specimen of phlogopite and diopside from the Franklin Marble, USA.
Lots of other fluorescent mineral grains on this specimen, its quite nice under 255nm but not really worth looking at under 310 or 365nm.
The Franklin Marble is an underlying rock formation rather than a specific locale.
This piece comes boxed with an ID label.
