Primary Birthstones for December 16
Tanzanite: The December Signature Stone
Tanzanite is a variety of the mineral zoisite, discovered in 1967 in Tanzania near Mount Kilimanjaro. It ranges from violet-blue to indigo, often showing pleochroism—displaying different colors when viewed from different angles. Its strong association with December makes it the default modern stone for December 16 birthdays. Tanzanite is valued for its rarity, clarity, and striking color, and it is the designated birthstone for December by many national gem associations.
Zircon: The Historical December Gem
Zircon is one of the oldest known minerals, with colors spanning blue, red, orange, yellow, and colorless. Blue zircon, in particular, has long been linked to December and is sometimes listed as a December birthstone in older references. It offers high brilliance and fire, often mistaken for diamond due to its dispersion and clarity. For December 16, zircon serves as an alternative with a rich historical pedigree and a wide palette of colors.
Turquoise: The Ancient Protector
Turquoise is a hydrous phosphate mineral recognized for its robin’s-egg to greenish-blue color and matrix patterns. While more typical for November, it is also cited in some traditions as a secondary December stone. It carries cultural weight across many civilizations and is commonly worn as a protective talisman. For December 16, turquoise provides a softer, more muted option compared to tanzanite and zircon, with historical significance and distinctive matrix character.

Durability and Everyday Wear
Durability varies significantly among December stones:
- Tanzanite scores 6.5–7 on the Mohs scale, making it suitable for dress jewelry with careful wear. It is sensitive to heat and sudden impacts.
- Zircon ranges from 6–7.5; higher-quality blue zircon is reasonably tough for daily rings if set protectively.

Regular cleaning with mild soap and water, along with avoiding extreme temperature changes, helps preserve these gems.
Buying Tips for December 16 Birthstone Jewelry
When selecting a stone for a December 16 birthday, prioritize clarity, color consistency, and treatment disclosure:
- For tanzanite, look for vivid violet-blue saturation and eye-clean clarity; small inclusions are acceptable if they don’t affect transparency.
- For zircon, choose a well-cut stone to maximize brilliance; note that some zircon is color-treated, so ask about origins.
- For turquoise, appreciate the matrix as a sign of authenticity, and favor stabilized material for jewelry to improve longevity.
Setting matters too: protective bezels for tanzanite and zircon, and hidden settings for turquoise, can reduce damage risk. Verify treatment status with a reputable jeweler or gem lab report when possible.
