Fluorescent Night: May 4
Explore the world of fluorescent minerals at the EIGGS clubhouse
If we can't have lightsabers, what better way to celebrate Star Wars Day than with glowing fluorescent minerals? Come to the club meeting Thursday, May 4 at 6:30 p.m. to see a wide variety of glowing gems and minerals and take a UV tour of the rock storage area in the garage. You will be amazed by what you find! If you have your own UV lights, bring them, as well as any fluorescent specimens or stones you wonder about. FYI, many jewelry pieces/gemstones glow, too. --Rubies, some sapphires, zircons, diamonds, amber, opal, Alexandrite, tremolite, etc.

Shortwave light90% of all fluorescent minerals need a shortwave light source. This is not your standard "black light." Below is a link to an inexpensive dual long/shortwave light several of our members recommend. It is low light and works best in dark conditions, but it is about the least expensive shortwave light you can get.

Longwave lightAbout 10% of fluorescent minerals show up under longwave light. Inexpensive ($5-12) longwave lights are readily available at a wide variety of locations such as Walmart, Meijer, Menards, Lowes, Amazon, etc. Be sure that they are labeled as UV lights and not just LED flashlights.
