March
Traditional: Bloodstone · Modern (1912 list): Aquamarine
The 1912 Jewelers of America list swapped this month's stone — both are shown above.
March is one of the months where the traditional and modern stones differ: the older stone is Bloodstone, while the 1912 Jewelers of America list added Aquamarine as a more commercially appealing alternative. Bloodstone is a dark green jasper flecked with red iron oxide, and Christian legend ties those red flecks to drops of Christ's blood at the crucifixion. Aquamarine's name is Latin for 'sea water,' and sailors historically believed it calmed rough seas and protected against seasickness.
March has a single birth flower, the Daffodil, with no alternate. It's one of the first flowers to bloom in spring, so it's read as a symbol of rebirth and new beginnings.
