Put sugar under an electron microscope and what do you get? A delicious rainbow of color. This highly magnified image of sucrose is printed on a translucent medium in order to give it a slightly luminescent look. The back of the 1" glass pendant is sealed with a jewelry-grade resin and is water resistant (although you should still not wear it swimming or in the shower). The bail is silver-plated and the pendant is hung on your choice of an 18" black cord, silver twist chain, or silver link chain.
