We interrupt the Spring Gem and Mineral Show to remind you to set your clock forward one hour tonight for Daylight Savings Time.

This clock is from the collection of David Reed. It contains agates, Apache tears (obsidian), a craft store clock kit, and lots of resin. It looks pretty good with his other rock clock.

Gold Sheen Obsidian
A dull gold oval-shaped stone resting comfortably in a person's palm. It is highly polished and reflects the overhead lights, and appears to have depth.

As viewed at the November 2014 meeting.

This is a gold sheen obsidian from the personal collection of our members M. Mueller and C. Maazouz. Obsidian is an igneous rock, which means it is formed from lava as it cools and solidifies. Obsidian is usually black. However, some types of obsidian have gas bubbles that create a gold or silver sheen like this.
