Customized December Birthstone Jewelry: Enchantment of Turquoise
published the “Gregorian Birthstone Poems” pamphlet which listed Turquoise as the birthstone for December. Then, in 1912, the National Association of Jewelers, which is now known as Jewelers of America, designated Turquoise as the primary December birthstone and lapis lazuli as the alternative December birthstone. In 1951, the Jewelry Industry Council of America added zircon to the 1912 list, which had turquoise and lapis as December birthstones. Today, Turquoise is considered to be the primary December birthstone, along with Zircon.
