Some people are interested in their "birth stones". I suspect that these lists are a fairly modern invention, just to sell gemstones! Still, for what it's worth, here are some versions of the list. These are all precious and semi-precious stones. The first column is the 'official' jewellers' list. The second has some cheaper alternatives for the expensive or hard to find gems (usually of roughly the same colour). The third is a Polish list, which is similar to the other two lists, but gives meanings as well.
