Sports: Holding a tennis racket tightly is particularly not good for a ring with stones going all the way around -- especially if you're left-handed. As for taking your ring to the gym, lifting weights with it on can be hazardous. You wouldn't want a heavy dumbbell making contact with your stone.
Gardening: It is possible to chip your stones or knock the settings loose while doing heavy yard work.
Cleaning house: It's a good idea not to wear your ring while doing the dishes: harsh chemical soaps or cleansers can soil the ring.
If you'll be taking your ring off to do the activities above, make sure you have a safe -- and memorable place to put it.
Keep It Free From Lotion, Sunscreen And Perfume. These products can gunk up your ring- it's a good idea to take it off before you apply product.
These products can gunk up your diamond, and even etch colored gemstones. It's a good idea to take your ring off before you put these things on.
Have Your Setting Checked Regularly.
Most jewelers recommend you have your setting checked every six months to make sure nothing has become loose.DON'T SWIM IN THE OCEAN WHILE WEARING YOUR RING! Cold water may shrink your fingers just enough to loosen the ring from your finger, and if you lose it in the deep blue sea, you won't be seeing it again.
Be Careful In The Kitchen. Cookie dough, turkey loaf, a piecrust… it's great to mix with your fingers. But these foods can leave a film on your ring and really affect its luster.
Don't Wear Jewelry In Swimming Pools and Spas - Chlorinated water can react with the metals found in jewelry causing color changes and even structural damage. As a result it's a good idea to remove jewelry before entering the pool or spa.
Remove Your Jewelry Before Bathing - Remove all jewelry before showering or cleaning. Soap can cause a film to form, making it appear dull and dingy. By preventing the formation of this film you immediately reduce the occasions of servicing. Use the cloth in the ring box to wipe the ring. You could bring it to a jewelry store but generally not needed.
Keep It Clean.
Most jewelers will clean your ring free of charge, so take advantage of this courtesy. If you don't have time to get to the jewelry store, there are a few ways to clean your ring at home.
Rinxe suggests using a gentle dish detergent to clean lotion buildup from the bottom of the mounting. Simply scrub the top and bottom with a soft toothbrush and rinse several times in hot water. For extra shine, soak your ring in a small bowl of ammonia diluted with three times the amount of water, and gently brush the top and bottom of the mounting with a soft toothbrush. Dip the ring into the solution again, then rinse in warm water several times to be sure to get all of the solution off. You may set the ring on a soft towel to dry, or gently pat it dry.
