Birthday Stones
gems considered particularly appropriate for birthday gifts. Any precious or semi-precious stone is considered appropriate as a setting in an article of jewelry intended for a birthday present. A preference for certain stones for certain months of the year has grown up, perhaps unconsciously. It would be difficult to trace the association between the month and the stone deemed appropriate. The popular list is:
| January | Garnet |
| February | Amethyst |
| March | Bloodstone |
| April | Diamond |
| May | Emerald |
| June | Lapis Lazuli |
| July | Ruby |
| August | Moonstone |
| September | Sapphire |
| October | Opal |
| November | Topaz |
| December | Turquoise |
