Some electrons get excited when struck by  ultraviolet light and give off unique colors, called fluorescence.  The picture above shows the same minerals in white light and short-wave ultraviolet light.  The quality of my camera does not do the color changes justice.

We have been home for a few weeks getting caught up on things and enjoying the unusually warm weather.  One project we finished was the new built-in mineral display cabinets – a project we started ten months ago!  We were excited to install our UV light for our fluorescent minerals, some pictured here.

This weekend we get back to one of our favorite shows, the Yucaipa Gem and Mineral Show, part of the city-wide Music Festival.  The Gem and Mineral show is around the corner of Yucaipa Blvd and Adams Street.  The show and festival start Friday evening and run through Sunday.  Hope to see you there.
