Obsidian is a popular lapidary material to collect and cut. Join Pasadena Lapidary Society at the April general meeting, as lapidary artist Terry Wilson takes us on a virtual trip to Davis Creek and other obsidian collecting locations, updating us on collecting site regulations. Terry will share tips on how to inspect the obsidian in the field and back at home. She will also demonstrate how to line up, slab and cab the material to bring out the best of their unique optical properties, including how to cut a cab exhibiting the cat-eye effect.
The April Rock of the Month will be presented by geologist, Dick Weber. Dick will take us on a tour of a hidden treasure: the Petrified Wood museum of Nebraska.

Pasadena Lapidary Society’s Tuesday, March 16 program meeting will feature geologists Dick and Mary Pat Weber, whose presentation will focus on the geological wonder of New Zealand. From volcanoes to glaciers, caves and fjords, finding so much variety of terrain in such a small geographical area would be impossible anywhere else on Earth.
The Webers are exploration geologists who spent a month in 2007 visiting every corner of this tiny island nation; they have worked and travelled extensively in North America, Australia and New Zealand.
