I've only just come across this as a thing very recently.
I don't know anyone in real life who does this?
I have expensive jewellery, engagement, wedding & eternity rings are in excess of 20k. And I generally wear a gold Anoushka necklace or similar.
I travel a lot for work & pleasure & I always wear my jewellery.
I generally only bring what I wear - I don't carry extras. But I've recently read about people having entire fake sets that they wear travelling
I'd hate that! Do you have fake jewellery just for travelling?
