Just like the alexandrite gem, the color of this distinctive square knob changes color right before your eyes. Under fluorescent lighting it's a pretty pale blue, and in natural light or under an incandescent bulb it shifts to a lovely lavender color. Made of lead-free German crystal and a solid-brass base, it comes in an array of our most popular finishes.
Dimensions: 1 3/16" square. Base: 1/2" W x 1/2" H. Projection: 1 9/16".
