Platinum can be used as a finish coating over sterling silver or copper alloys. Its bright, pure luster enhances the brilliance of gemstones and does not discolor or oxidize. Platinum plating is also characterized by its good resistance to surface abrasion, making jewelry pieces more durable against everyday and long-term wear. Over time, platinum plating will wear off and therefore will require re-plating.
To care for your plated jewelry items:
Remove jewelry before bathing, swimming, washing hands, putting on make-up, lotions, perfumes, and/or working with household chemicals, cleaners, or acidic liquids.
Do not clean plated jewelry in an ultrasonic cleaner or in silver cleaning solutions, as it could completely remove the plating finish from your item.
Ensure your jewelry item is thoroughly dry before storing. Moisture in an enclosed space can increase tarnishing.
Store your plated jewelry in a jewelry box lined with felt or anti-tarnish material. Items should not be stacked as this may cause damage to the plating surface.
Do not use excessive pressure when cleaning with a polishing cloth or soft brush, as this may cause damage to the plating.
Over time your plated items will need to be re-plated. Contact your local jeweler for information on plating services.
Earring Back Types
The backing is an important part of an earring, providing a secure closure and comfortable fit. Keep in mind, some earring styles work better with certain back types. Experiment with the different types to find the best fit for you!
Butterfly Back: A double looped piece resembling a butterfly that fits over a post. Variations on this design are called push back clasps. The basic post and butterfly back are usually used for stud earrings and lighter weight drop earrings.
Hinged Snap Backs: This clasp features a hinged post that snaps into a groove on the back of the earring. It is commonly found on hoops. Sometimes the hinged post is curved to provide more room to fit around the ear, sometimes called a saddleback.
Hook Backs: This earring backing is simply a long, bent post that fits through the piercing. Hooks have several variations, most notably the shepherd's hook and the French hook. While thin wire hooks reduce the weight of long earrings, making them more comfortable, they aren't as secure as other clasp styles.
Lever Back: A hinged lever snaps shut against the curved post to form a closed loop around the ear lobe. This clasp is very secure and good for large or medium sized styles that drop just below the ear.
Omega: Also called French clips, this clasp has a straight post and a looped lever. The hinged lever closes around the post and is held against the ear with pressure. The omega clasp is the most secure clasp, especially for the larger, heavier earrings.
Screw back: This backing is a slight variation of the standard post and butterfly nut back. Instead of pushing on the back, the nut twists onto the threaded post. A screw back post design is often preferred for expensive diamond stud earrings that require increased security.
