You can wear them in the water because they are 14 k gold
Love these earrings. They were a little smaller than I thought and the clasp gets wonky after a while.

These have been a conversational piece
Style: 16mm Rose Gold
I thought these were cute. I purchased two sets because I have two holes. They seem like a good quality of rose gold. They are not to big but the heart just hugs my ears.
