The most likely way that hoop earrings, or any jewelry for that matter, might be damaged is when you travel. With hoops, it's important to separate each one from the other and surround each individual hoop with a soft
material. Then take the separately wrapped hoops and put them both in
a small cardboard or metal box to carry in your purse or in your
suitcase. This will protect them from other objects damaging them.
The most dangerous way to travel with
hoop earrings is to place them loose in your change purse (almost
guaranteed to damage them!) or in a side pouch in your purse.
Everything else that is carried in that purse is bound to push up
against the earring and since the earring is either hollow or
somewhat thin, it can be damaged easily.
If you find you are caught
without packing supplies or jewelry boxes, take each hoop and wrap it
with a couple tissues, making it bulky and round around each hoop.
Remember not to pack the hoops next to each other in the same tissue
or they can damage each other! Then put the very puffy hoop earring
“tissue packages” inside a sandwich bag and put it as high up in
your purse as possible so things aren’t lying on the package.
Sorry to say it but hotel rooms are a
common place to either misplace your jewelry (by putting it in some
“hidden place” and then forgetting it) or have it stolen
because you left it out exposed. Always use the room safe and if the
hotel doesn’t provide them, ask to keep your valuables in the safe
deposit box behind the front desk. If you must hide your hoops, tell
your companion where and to remind you or send yourself an email or
text about it!
