By | April 4, 2014

Wednesday, 2nd April 2014 – “Spectroscopy, gemstones and minerals”. Keith Snell, leader of the U3A Geology group, gave a very interesting talk about the use of Spectroscopy in the analysis of minerals and in the gems trade. Illustrated with some very colourful slides, and pieces of his own home-made equipment, Keith’s talk was laced with personal anecdotes of his interest in gems and minerals throughout his life.
