December birthstone
For December you have four possible birthstones: turquoise, tanzanite, zircon, and the Ayurvedic ruby. Turquoise offers a serene, ancient sky blue that feels like a quiet sky; tanzanite brings a rare violet-blue found only in one place on Earth; zircon dazzles with bright, fiery flashes in many colors but especially blue; and ruby delivers a deep red for those following the Ayurvedic calendar.
December’s stones across the traditions
History & lore
Turquoise has been prized since antiquity by Egyptians, Persians, and Native American peoples, used both for ornament and as a protective amulet. Tanzanite was discovered only in 1967 in Tanzania, making it a modern addition to the birthstone list. Zircon has been known for centuries, often confused with diamond due to its brilliance, while the Ayurvedic ruby reflects the ancient Indian tradition of linking gemstones to planetary bodies for balance.
What it’s said to carry
Traditionally, turquoise is said to offer protection and to bring good fortune to its wearer. Tanzanite is associated with spiritual insight and the opening of the heart to higher consciousness. Zircon is believed to promote restful sleep and to ward off negativity, and ruby has long been linked in many cultures to passion, vitality, and courage.
Wearing & choosing it
You might choose your December birthstone based on the color that speaks to you most: turquoise often contains dark matrix lines, tanzanite is softer and best set in protective jewelry, zircon is quite hard but can chip, and ruby is extremely durable. For everyday wear, turquoise and zircon are practical choices, while tanzanite and ruby suit occasional wear or thoughtful setting. Consider your lifestyle and the shade you love when selecting a piece.
