Abstract
An ornamental ring having a flashing capacity controlled by a minute electrical circuit incorporating one or more light-emitting diodes which are confined in the gem-display region of the ring, is disclosed. A time delay, capacitor-resistor arrangement governs the activation and deactivation of a pair of transistors whose function is to cause the light-emitting diodes to alternately flash or blink in substantially identical intervals.
