Why don't jewelry stores want you to know how to make your used jewelry look like new. Simple!
They wouldn't sell you something new.
We sell a lot of Tiffany, David Yurman, Konstantio and John Hardy sterling silver jewelry at Posh Designer Jewelry, and the most frequent question we get is how to make it look like new again. Its really pretty simple yet the results are amazing.
To demonstrate how easy this is, here is a preowned Tiffany & Co. necklace recently purchased at a estate sale. The pendant sold for quite a bargain. It was badly tarnished and the auctioneer was unaware or uninterested in taking the time to clean it up. After examining it closely and finding no deep scratches, we decided to purchase it.
Make a small batch of household ammonia and hot water. Use about a cup of hot water and a tablespoon of ammonia. Soak the sterling silver piece the solution for about 10 minutes. This removes all the dirt and grime that has built up over time. After soaking blot it dry with a paper towel or cotton cloth. This works with any designer brand jewelry.
This is where the real magic happens. We use Wright's silver cream polish. We have tried a lot of other products, but none seem to perform as well as this one. You can get this at most grocery stores, Walmart, or online. It comes with a sponge applicator. Apply a little polish to the applicator and start rubbing it all over the piece you want to polish. Take your time and really polish the piece thoroughly. If the sponge applicator becomes black and dirty your can rinse it out and squeeze it dry. Some pieces I may spend 10 min or more polishing over and over.
Give the bracelet, necklace, or earrings a good rinse under hot water to remove any polishing compound residue. Then mix up a fresh batch of ammonia and hot water. Again, let the piece soak for a few min. Now you are pretty much finished. Remove the jewelry from the soaking solution and blot it dry.
If you have a silver polishing cloth you can optionally buff the piece with this for even more shine, although I honestly don't think this step is necessary.
The results of this process will be astounding on your used jewelry especially if hasn't been polished recently. This process is good for any of the major designer brands Tiffany& Co., John Hardy, David Yurman.
