Things To Avoid When Wearing Your Ring

We know you ADORE your ring!
But doing certain tasks with your diamond ring on (and that really goes for any jewellery) can wear down the metal.
This can cause stones to come loose, cracks in the metals, or even worse, your diamond to fall out.
While we’re happy to repair anything that comes through our doors, we’d never want you to loose a diamond!!
A diamond ring or even a simple gold wedding band, in addition to being an investment over time, is also a piece of jewellery that can be easily damaged.
So, we thought you ladies (and gents) could use some tips on what NOT to do while wearing your rings.


It seems simple enough, and we know you want to keep from getting hit on at the gym, but…. just don’t do it!
Especially with gold, a softer metal that can wear over time, gripping hand weights, bars and even the elliptical machine can crack or even break a band.
Plus, sweat will dull your finish.
Fitness is important, but please try to remember to take your rings off before your sweat session.


House-hold cleaners and bleach are really rough on gold and precious metals.
Be sure to remove your “precious cargo” before scrubbing the grout and you should be just fine.
Rubber gloves are an alternative, just ensure your rings aren’t pressing on anything heavy, like the handle of a pan.


So many things today are all about DIY, especially for your wedding, but stow the rings somewhere safe before you get started.
The ingredients and final product of craft-time can get in between diamonds and any other tiny openings of your ring.


This is just as dangerous for your rings as working out.
Find a safe ring box to stow in your gym bag/locked locker.
No one wants to see their diamond ring fly across the floor or tennis court… or to the bottom of a lake!
Swimming is also one of the worst… the chlorine (or salt water) is SO rough on your precious piece.


If you’re moving, and you’ve already packed up the rest of your jewellery, why not add your rings to that box?
This way you’ll know where to look while you’re unpacking and you won’t have to worry about the damage that can occur while you’re trying to move the couch into the living room or getting the box spring up the stairs.


Now, we understand that laundry isn’t necessarily a heavy-duty job (for most) but we wanted to throw this in, just in case.
Be careful when loading & unloading the washing machine.
You’d be surprised how easy it is to whack your ring along the rim of the drum or scrape it down the side while reaching for the wet clothes.
You can chip your diamond this way or cause damage to your mounting, especially if you have a ring that holds your diamond up higher.
Plus, you don’t want to accidentally snag it on clothes you love while folding.


We see it all the time, especially with women who love to spend time in their flower beds.
However, the dirty truth about gardening with your ring on is that the dirt can get lodged in the smallest places and settle beneath your diamond, making the whole set look dingy and dirty.
The dirt and rocks can even scratch up the ring itself.
Wearing gardening gloves if you must, but we recommend you leave your ring in the house altogether.


In follow-up to your cleaning routine, if you moisturize your hands just out of the shower or throughout the day, be sure to take your rings off before slathering it on.
The chemicals in lotions can eat away at your gold and make your diamonds and metal look dirty, especially if you let the lotion residue sit on your rings for a long time.
It’s an easy clean by a jeweller, but because of that breakdown over time, we still recommend you take them off beforehand.


This is probably the biggest no-no!
Water, soaps and chemicals in your cleansers will break your ring down over time.
If your ring is prong-set, especially, the prongs can possibly thin out… and there is already little metal holding that beauty in place.
Plus, as with the other items we’ve already discussed, soap and hard water make your ring dirtier rather than clean.
Nobody wants to show off a ring that doesn’t sparkle beautifully!


Last, but not least, we highly recommend that you don’t sleep with your rings on.
You and your spouse could easily wake up with battle wounds.
Not to mention you can create a pretty nasty hole in the sheets if you catch the ring just right.
Putting your ring in a safe spot for the night will ensure a good night’s rest of all parties involved.
