The Ultrasonic Jewelry Cleaner.

Using sound waves and plain tap water, this ultrasonic jewelry cleaner removes dirt and dust particles from most rings, bracelets, and necklaces without manual scrubbing or harsh chemicals. The cleaner generates 42,000 Hz of ultrasonic sound waves that penetrate deep into crevices to safely and effectively clean intricate areas of treasured heirlooms. It has a 20-oz. stainless steel tank (for proper soundwave impedance) and an easy-to-read maximum fill line. The cleaner features whisper-quiet, solid-state circuitry, a three-minute auto-shutoff setting, and a viewing window with a light that illuminates the interior. Also suitable for precious metals and gems, waterproof watches, CDs, dentures, and eyeglasses.
