The list of birthstones varies with where you read it. Some of these lists include lapis lazuli which is a rock and not a mineral and pearl which is also not a mineral but an organic gem. The rest are minerals.

Birthstones are reported to have been based on a particular set of 12 stones that were set into the breastplate of Aaron, brother of Moses. The stones represented the 12 tribes of Israel, the 12 signs of the Zodiac, or the 12 calendar months.
Birthstones are minerals.
Common minerals can be identified by inspecting or testing their physical properties such as:
color, streak, transparency, luster, hardness, cleavage, fracture, specific gravity, and crystal form.
