Our Tuesday, January 18, 2022 Program Meeting will be held via Zoom. PLS member David Lacy will provide the evening’s presentation as an overview of Crystals and Crystal Forms.  We will look at the differences between geometrical (ideal) crystal forms and some of the crystal habits in nature, where geometric forms meet the real world.  We will check on just what are the characteristics of a crystal, what is a crystal habit, symmetry in crystals, and the seven crystal systems met in nature.  Some mineral specimens will be visually shared to demonstrate real-world crystal habits. Meeting starts at 7:00 p.m. If you’d like to join us, write marcia.pls.emails [at] gmail [dot] com to request a Zoom link.
