I purchased these for a friend who loves the ocean.  The earrings were very well received and she has already worn them out.  The shells are quite pretty on both sides but the white part with the swirl is what actually shows.  The white part has a nice shimmer or pearly quality.  The earrings are about an inch and a half long and a three quarters of an inch wide.  They are the perfect size for day or evening wear.  The only issues I have with these earrings are that one shell was slightly larger than the other and there was a small indent on the back side of one of the earrings.  It did not bother me too much since these are made from natural shells but it is something to be aware of as you go to buy them.  Overall, I would recommend them since they are a great price and pretty.
