December’s birthstones offer three ways to fight the winter blues: tanzanite, zircon and turquoise – all of them, appropriately, best known for beautiful shades of blue.
These gems range from the oldest on earth (zircon), to one of the first mined and used in jewelry (turquoise), to one of the most recently discovered (tanzanite).
All of these stones are relatively inexpensive, but their beauty rivals even precious gems. Colorless zircon is a convincing replacement for diamond, tanzanite often substitutes sapphire, and turquoise is unmatched in its hue of robin’s egg blue.
Whatever your style preference or budget, one of December’s three birthstones will match your true blue desires.
Tanzanite
The common story of tanzanite’s discovery tells of Maasai herders who found blue crystals in the Merelani Hills near Arusha, Tanzania, while tending livestock in 1967. They notified a prospector named Manuel d’Souza, who promptly registered claims with the government to begin mining.
Admired since ancient times, turquoise is known for its distinct color, which ranges from powdery blue to greenish robin’s egg blue. It’s one of few minerals to lend its name to anything that resembles its striking color.
Turquoise
The word turquoise dates back to the 13th century, drawing from the French expression pierre tourques, which referenced the “Turkish stone” brought to Europe from Turkey.
The U.S. is now the world’s largest turquoise supplier. Nevada, New Mexico, California and Colorado have produced turquoise, but Arizona leads in production by value, as well as quality. The stone’s popularity here makes it a staple in Native American jewelry.
Turquoise is found in arid regions where rainwater dissolves copper in the soil, forming colorful nodular deposits when it combines with aluminum and phosphorus. Copper contributes blue hues, while iron and chrome add a hint of green.
Zircon
Zircon is an underrated gem that’s often confused with synthetic cubic zirconia due to similar names and shared use as diamond simulants. Few people realize that zircon is a spectacular natural gem available in a variety of colors.
The name zircon likely comes from the Persian word zargun, meaning “gold-colored.” Others trace it to the Arabic zarkun, meaning “vermillion.” Given its wide range of colors – spanning red, orange, yellow, green, blue and brown – both origins make sense.
