Done drawing all of the birthstones for my 2014 calendar! Around the circle beginning with the diamond:
diamond (april), sardonyx (august), garnet (january), amethyst (february), bloodstone/heliotrope (march), agate (june), sapphire (september), turquoise (december), opal (october), topaz (november), ruby (july), and in the center, emerald (may).
These are the traditional Gregorian birthstones, which means you can go on the wikipedia page and read fun poems about your birthstone.
“The February-born shall find
Sincerity and peace of mind,
Freedom from passion and from care,
If they an amethyst will wear.”
