This is an absolutely stunning necklace. The easily replaceable battery* is in the clasp. Shutting the clasp completes the circuit, lighting the light-emitting diode (LED).
The flame orange LED is embedded within a genuine Swarovski® crystal. A warm orange glow is created as the light exits the crystal. This combines with ambient light that is reflected and refracted to complete the effect. Great for those cold nights!
Light-emitting diodes (LEDs) are the scientific opposites of piezoelectric solar panels. In that case, light causes a current to flow. With an LED, the current causes the light to shine.
Dimensions: 17" (43.2 cm) long coated metal wire, 2/5" (1 cm) cubic-based crystal.
*Battery: included 3 Volt lithium. Runs about 60 hours.
