Tanzanite, Zircon, Turquoise
Meaning & lore
Turquoise has carried protective associations in many traditions; zircon also appears in protective folklore. You can treat these stories as a starting point for a personal gift message rather than a promise of protection.
History & origins
Turquoise was worn in ancient Egypt. Tanzanite entered modern jewelry much later, after its source was located in Tanzania’s Merelani Hills in 1967. Blue zircon was popular in Victorian jewelry.
Choosing a personal gift
Choose by the kind of blue the wearer loves. Tanzanite leans toward violet, blue zircon brings a lighter look, and turquoise gives an earthy, opaque finish. A December birthday gift need not follow winter colors: match the wearer’s year-round wardrobe. A simple setting lets the chosen color take the lead.
Check sizing before choosing a bracelet, necklace or ring.
A note on care
These gems need individual care. Avoid ultrasonic and steam cleaning for tanzanite and turquoise, and protect zircon from abrasion. Find everyday habits in our jewelry care guide.
