Bull and Bear Black Paperweight
The bull and bear are atop a 4 inch square of black and white marble. They are made of brass then gold plated which makes them tarnish proof.
Customization would be done with a plaque. You could actually have two lines of text if you'd like. This is no lightweight paperweight, it weighs 1-1/2 lb. The plaque will be mailed to you separately.
Wall Street Gifts offers several desk items made with black and white marble.
