Our Natural Brilliance Jewelry cleaner, comes in a hourglass bottle, that allows you to clean your jewelry without brushing or vibrating your jewelry, which could cause the weakening of prongs and stone loss. Insert jewelry in hourglass, tighten the lid and turn upside down. Let jewelry soak, then turn right side up. Gold, Silver and all other hard metals can soak overnight to loosen the buildup of hand lotions, body oils, hair spray and etc. Opals, Pearls and fashion jewelry should only soak for five minutes each time. Opals and Pearls need the moisture back in them, but a little at a time. Fashion jewelry is held together with glue and soaking for long periods of time can turn glue loose. You may soak Opals and Pearls every day, but not all day long. Recommended time for Opals, Pearls and Fashion jewelry is five minutes each time. Our jewelry cleaner will transfer to opposite side bubbling through the jewelry, gently removing dirt without the harmful effects of a toothbrush, (which can weaken prongs and loosen stones.) After cleaning, rinse jewelry with clear water, and pat dry. There is no need to shake our hourglass, because vibration can also loosen stones. Even though you may place numerous pieces of jewelry in the hourglass at one time, it is recommended to clean jewelry that is easily scratched, such as Opals and Pearls separately.
