December's Triple Gem Delight

Blue Zircon, Blue Topaz, and Tanzanite

December is a month full of celebration and connection. The birthstones for this month embody this same spirit, and there are actually three! Each gem possesses its own one-of-a-kind charm, unique background, and set of characteristics that are sure to enchant all who appreciate precious stones. Whether you were born in December, or simply enjoy the beauty and history behind gemstones, we believe you will find admiration for these birthstones. 

The Gemstones for December 

Blue Zircon

Regarded as one of the contemporary December birthstones, blue zircon, scientifically known as zirconium silicate, is valued for its high refractive index. Its exceptional fire and luster emulate the brilliance of a diamond, surpassing that of sapphire, ruby, or tanzanite, among other distinctive qualities. 

Zircon is initially found in a brown hue but undergoes a transformation to blue through heat treatment. Many zircons feature prominent green undertones, contributing to the gem’s distinctive coloration. High-quality blue zircons showcase vibrant green tones with moderate color saturation. Historically, the transformation to blue through heat treatment was predominantly associated with Cambodian and Burmese zircon. However, recent discoveries have revealed blue zircon occurrences in Maripa, located in southern Malawi.

Blue Topaz

Blue Topaz has been cherished for thousands of years, with ancient Egyptians believing it had protective powers. It gained popularity in Europe during the Renaissance. Available in various shades of blue, blue topaz is sought after for its calming and cool tones. It is often associated with loyalty and communication. Blue topaz is made of aluminum and fluorine and is a silicate mineral characterized by its glass-like luster and distinct cleavage, making it delicate and brittle.

Natural blue topaz deposits can be found in the state of Texas in the United States and the Ural Mountains in Russia. Additionally, Brazil, Sri Lanka, Nigeria, and China contribute to the global production of blue topaz.


Tanzanite is a relatively recent discovery, found in the foothills of Mount Kilimanjaro in Tanzania in 1967. It quickly gained popularity for its captivating hues. Originally mistaken for sapphire, tanzanite was recognized as an entirely new variation within the zoisite gem species. Tanzanite owes its name to Tiffany & Co., a prominent global distributor that recognized the gem’s potential upon its discovery. In an effort to enhance consumer awareness of this unfamiliar stone, they aptly named it in tribute to its African place of origin, Tanzania.

Tanzanite is renowned for its trichroic nature, which means the gem displays different colors from blue to violet depending on the crystal’s orientation. Every glance at your tanzanite jewelry reveals something distinct and dynamic. Currently, Tanzania is the only place this gem is mined. Its rarity adds to the gemstone’s allure.
