What you need :
The jewelry you want to save
Clear Nail Polish
... That's it!
Paint the inside of your watch , ring , bracelet etc with clear nail polish. It creates a nice layer that keeps the original color of the jewelry on the piece and off your skin!
* Another great tip to put your clear nail polish to good use: When you have jewelry with small crystals, you can also use the clear nail polish to keep those little bling pieces from falling out. Just do the same as above ,paint a layer or two of clear polish on top and it will keep your bling in place. :) it's a pleasure! :D
