Birthstones are a fun way to say "Happy Birthday" to a special someone. Birthstones are sometimes used as anniversary gifts as well bought gifts lack. Many also beleve that the birthstone that pertains to an individual's month brings good luck.
Although not commonly given as gifts (most couples follow the usual anniversary gift list), certain gemstones correspond with wedding anniversary years. Actually, there are several lists, and they don't often agree. Have fun perusing the different lists in the External Links section below, but don't put too much stock in them. A quick glance is enough to show you that they vary considerably. You're probably better off with the traditional or modern gifts if you are bent on an "appropriate" gift for a particular anniversary; those lists are more or less standardized.
