How to Clean Gemstones Jewelry
Regular cleaning can keep your gemstone jewelry looking bright and sparkly for a lifetime and longer if you use the proper method.
Before cleaning, be sure to check that the settings, prongs, clasps and mountings are secure and that there are no loose stones. If there are any problems with these parts, take the jewelry item to a reputable jeweler for repair. The jeweler can also clean the item for you at this time.
Peridot, blue topaz, tourmaline and tanzanite can be fragile or porous. Harsh cleaning solutions can enter the gem through the microscopic holes and damage the gem over time. These delicate gems need gentle cleaning. They should not be exposed to ammonia, heat, ultrasonic cleaning, or any abrasives. They can be cleaned in warm soapy water and a clean soft bristle brush. Make sure to rinse well in cool water and allow drying thoroughly before storing.
Opaque gemstones like jade, lapis,turquoise necklace, malachite or onyx are essentially rocks, not crystals as in transparent gems. Like your average rock, they are porous and will absorb water, soap or any chemical you put them in. For that reason, soaking them should be avoided as they can become discolored from the soaking solution, even a mild soap and water. The best method of cleaning them is to wipe them gently with a moist cloth. Never use an ultrasonic cleaner, a brush or ammonia for cleaning them. Coral and amber are also best cleaned using this method.
Opals like opal necklaces are hardened silica gel containing 5 to 10 percent water. Special care is needed in cleaning them to avoid drying them out. Simply wipe them gently with a moist cloth. Never use heat, an ultrasonic cleaner or ammonia when cleaning them.
An ultrasonic jewelry cleaning system uses only water and ultrasonic energy which is transmitted into vibrating energy waves. Make sure that you select a model that uses an ultrasonic transducer as some call themselves ultrasonic cleaners but only have a motor that causes vibrations. The motion of the ultrasonic waves creates millions of microscopic bubbles in the water or cleaning solution. When the bubbles bump into the jewelry, they gently penetrate the crevices and clean them out. Gemstones that are generally safe to clean using this method are alexandrite, amethyst, aquamarine, cubic zirconia, diamonds, garnet, sapphires and quartz.
With proper cleaning and good care, your fine jewelry can be kept looking new for years to come.
