December’s birthstone, blue zircon, is a gemstone that combines natural beauty with symbolic significance. While zircon itself is an ancient mineral with a long history in jewelry and mythology, the blue variant—often created through heat treatment—has become a popular choice for modern birthstone jewelry. This article explores the properties, cultural significance, and practical care of blue zircon, as well as its place in contemporary collections, particularly through the offerings of Alex and Ani and other brands.
Introduction
Blue zircon, the December birthstone, is a gem that stands out for its brilliance and affordability. Though not as widely recognized as diamonds or emeralds, blue zircon has a unique charm and a rich history. In the modern era, it has been embraced by jewelry designers and consumers alike, especially through customizable and symbolic collections like those from Alex and Ani. This article will explore the historical and cultural significance of zircon, its geological formation, and how it is used in today’s jewelry, particularly in December-themed pieces.
History and Lore
Zircon is one of the oldest minerals on Earth, with some zircon crystals dating back over 4.4 billion years. However, its use in jewelry is relatively recent. In ancient times, zircon was sometimes mistaken for other gemstones like diamonds or topaz. It was also believed to possess mystical properties.
In medieval Europe, zircon was thought to have protective powers. Travelers carried it to ward off nightmares and to ensure safe journeys. In India, zircon was considered a powerful stone for prosperity and was often used in religious ceremonies. The name "zircon" is derived from the Arabic word "zarkun," meaning "gold-like," referring to the yellowish or golden tones of natural zircon before it was heat-treated.
The blue variant of zircon became popular in the 20th century after it was discovered that heating natural brown or yellow zircon to high temperatures could transform its color to a vivid blue. This heat-treated blue zircon is the form most commonly associated with December birthstones today. Unlike diamonds or emeralds, blue zircon is relatively affordable and accessible, making it an appealing option for those seeking meaningful yet budget-friendly jewelry.
Geological Formation and Sources
Zircon is a zirconium silicate mineral that occurs in a variety of colors, including brown, yellow, red, green, and colorless. The blue zircon used as a birthstone is typically created through a heat treatment process that changes its chemical structure and imparts a blue hue. This treatment is stable and permanent, making blue zircon a durable and attractive option for jewelry.
Natural zircon is found in several parts of the world, including:
- Brazil: One of the major sources of zircon, Brazil produces zircon in various colors, including the yellow and brown variants used for heat treatment.
- Australia: Known for high-quality zircon deposits, particularly in the New England region.
- Madagascar: A significant source of zircon, including some of the finest material for jewelry.
- India and Sri Lanka: These countries have a long history of zircon mining and trade.
Zircon forms in igneous rocks and is also found in metamorphic and sedimentary deposits. It is resistant to weathering and can be found in beach sands, where it is often panned or mined for use in industrial applications and gemstone production.
Gemological Properties
Blue zircon is a popular gemstone due to its vibrant color and relatively high refractive index, which gives it a brilliant sparkle. Below is a summary of its key gemological properties:
| Property | Description |
|---|---|
| Chemical Formula | ZrSiO₄ |
| Color | Blue (heat-treated form); natural colors include yellow, brown, red |
| Hardness (Mohs Scale) | 6–7.5 |
| Refractive Index | 1.92–2.01 |
| Specific Gravity | 4.6–5.0 |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Cleavage | Indistinct to none |
| Treatment | Heat-treated to produce blue color |
Blue zircon is relatively durable for a gemstone but should be handled with care due to its moderate hardness and lack of cleavage. It is not as hard as diamonds (10 on the Mohs scale) or sapphires (9), so it can be scratched by harder materials. However, it is more durable than many other colored gemstones, making it a good choice for everyday jewelry.
Symbolism and Metaphysical Beliefs
Throughout history, zircon has been associated with a variety of symbolic and metaphysical properties. In ancient cultures, it was believed to promote happiness, good health, and protection. Some traditions suggest that zircon can enhance intuition and help with emotional balance.
In modern times, zircon is often associated with positive energy and spiritual clarity. It is said to bring a sense of calm and stability, making it a popular stone for those who seek inner peace and emotional strength. Some metaphysical practitioners believe that blue zircon can enhance communication and encourage truthfulness.
As the December birthstone, blue zircon is also seen as a symbol of new beginnings and the hope that comes with the winter season. It is often given as a gift to celebrate birthdays, anniversaries, and other milestones, symbolizing the warmth of friendship and the promise of a bright future.
Care and Cleaning
Due to its moderate hardness and vitreous luster, blue zircon requires proper care to maintain its beauty and durability. Here are some tips for cleaning and preserving blue zircon jewelry:
- Avoid Harsh Chemicals: Clean zircon with mild soap and warm water. Avoid using harsh chemicals or abrasive cleaners, which can dull the gemstone’s surface.
- Use a Soft Cloth: Gently wipe the gemstone with a soft, lint-free cloth after wearing to remove dirt and oils.
- Avoid Extreme Temperatures: Although zircon is stable after heat treatment, it is best to avoid exposing it to extreme temperatures, such as those found in steam cleaners or ultrasonic cleaners.
- Store Separately: To prevent scratches, store zircon jewelry separately from harder gemstones like diamonds or sapphires.
- Professional Cleaning: For more thorough cleaning, consider having the jewelry professionally cleaned by a jeweler.
With proper care, blue zircon can retain its brilliance and beauty for many years, making it a lasting and meaningful addition to any jewelry collection.

The use of blue zircon as a December birthstone is relatively recent compared to other gemstones like diamonds (April) or emeralds (May). However, its popularity has grown significantly over the past few decades, especially with the rise of customizable and charm-based jewelry.
The choice of blue zircon as a December birthstone is largely due to its affordability, durability, and striking color. It is also a versatile gemstone that can be used in a wide range of jewelry styles, from elegant pendants to bold statement pieces.
