Modern birthstone

The modern January birthstone list, established by the American National Association of Jewelers in 1912 and updated periodically since, includes: Garnet.

Traditional birthstone

The traditional birthstone list (drawing from older European and Polish gem-month associations) for January includes: Garnet.

Where Zultanite fits

Not an official January birthstone — Zultanite’s sage-green daylight phase pairs visually with garnet’s deep red, but the gems are mineralogically unrelated.

How birthstone lists work

There is no single global authority on birthstones — modern, traditional, mystical (Tibetan), and Ayurvedic lists all differ. Zultanite was discovered too late (commercial production began in the early 2000s) to enter any of the historical lists.
