Done fairly quickly, this is a crystal lamp I made for a friend. It is made from quartz crystal and plumbing fittings! The jade green color it glows was achieved with the use of an RGB LED with full voltage to the green diode and a little bit of voltage to the blue diode. It runs on a nine volt battery, has a nice little metal toggle switch, and the bottom screws open to reveal the battery inside! Done five months ago.

This is the beacon with no power to the LED.
