Tues Oct. 16, 2018,  7pm – 9pm    October FM-NJ Meeting
Presenter:  John Sanfacon

Lecture Topic:  Synthetic vs Natural Minerals and Gemstones

Definitely a very neat and interesting presentation on what we see today commercially as far as gemstones and minerals that are often synthetic.  Small instruments and meters will be brought in to demonstrate what jewelers and appraisers use to tell cubic zirconium, fake rubies and diamonds, and a host of other “dead ringers”, from their real counterparts.  One presentation you do NOT want to miss!!!

Field Trips

In conjunction with the North Jersey Mineralogical Society, FMNJ runs field trips to mineral and fossil deposits in the MD, DE, PA, NY and NJ region to collect specimens. See our Trips page for recent and upcoming trips.
