In many cases jewellery can indeed be cleaned at home. A gentle solution of mild liquid soap and warm water in a small bowl is a simple and easy way to do so. A soft tipped brush may be used around stones and settings, and once dry, wiped down with a soft cloth. A word of warning, do proceed with caution and always check with your jeweller before attempting to clean at home. Nothing beats a professional clean and polish by your local jeweller. Do note that some stones, settings, and metals, require specialist care and are best cleaned by a jeweller.
