They do. Opals will crack if you just put them away in a jewelery box. they are a water stone and will actually dry out and *snap!*. It's recommended that you touch your opals often (for the oils to "moisturize" the stones) and thay you don't "dry store" them for extended periods of time.
I too wore those earings all the time but the shower was seriously hot. It's also said that you should never buy opals for yourself (they will crack) and only accept opals from someone you truely love (or they will crack).
