I go weak in the knees for pretty faux pearls. I love the weightiness of glass pearls, but lustrous plastic ones are OK by me, too. I especially love pearls with details on the clasp, like molded metal or rhinestones. There's a feeling I get from wearing pearls - even when they aren't real! - that I don't get from any other type of jewelry. Sort of blasé and stately at the same time.
