Blue zircon is a gemstone often celebrated for its exceptional brilliance and fire, frequently likened to that of a diamond. As a primary birthstone for December, it offers a vibrant and often overlooked alternative to other popular December stones like blue topaz and tanzanite. However, it is crucial to distinguish it from cubic zirconia, a synthetic diamond simulant, as the two are frequently confused. This article will delve into the history, geological origins, gemological properties, symbolism, and care of this captivating gemstone, drawing solely from available sources.
History and Lore
While specific historical details are limited within the provided sources, blue zircon carries a rich tradition of symbolism and belief. Traditionally, it is associated with wisdom, confidence, and prosperity. Throughout history, and continuing today, it has been believed to ward off negative energies and evil spirits, creating a protective aura around the wearer. Beyond general protection, zircon is thought to aid in achieving restful sleep and enhancing dream clarity, as well as improving intuition and perception.
More recently, blue zircon has gained recognition for its potential benefits to creative professionals. It is believed to enhance creative energy for writers, boost artistic vision for painters, and improve musical creativity and expression for musicians. These associations highlight the stone’s perceived ability to unlock and amplify inner talents.
Geological Formation and Sources
Natural blue zircons are exceptionally rare. The vibrant blue color seen in most gem-quality blue zircons is achieved through heat treatment of naturally occurring brown zircon. The sources best suited for producing material that responds well to this heat treatment are Cambodia and Myanmar. More recently, Malawi has emerged as a promising new source of zircon rough, with notable heat-treated blue zircons reportedly originating from the Maripa region.
The sources indicate that the gemstone itself can achieve a hardness of up to 7.5 on the Mohs scale, indicating good resistance to scratching. However, zircon is notably brittle, making it susceptible to chipping and breaking upon impact.
Gemological Properties
Zircon’s appeal lies significantly in its optical properties. It is highly refractive and exhibits intense fire, meaning it displays a vibrant play of color similar to diamonds. The finest blue zircons display hues with strong green components and medium tones. Trade names sometimes used for blue zircons include “starlites” or “stremlites.”
While zircon can occur in a variety of colors, heat treatment is commonly used to produce the desired blue shades. Other colors achievable through heat treatment include green, red (a rare and prized color), colorless (maximizing brilliance), and honey gold. The provided sources detail a typical stone size of 3mm, as seen in a 14k gold ring, and also mention sizes of 6mm and 8mm set in tungsten bands. A 3mm stone has approximate top dimensions of 4.04mm x 4.04mm.
The following table summarizes key gemological properties based on the provided sources:
| Property | Value |
|---|---|
| Mohs Hardness | Up to 7.5 |
| Fire | High |
| Refraction | High |
| Common Colors | Blue, Green, Red, Colorless, Gold |
| Typical Sizes | 3mm, 6mm, 8mm |
| Treatment | Heat Treatment (for blue color) |
Symbolism and Metaphysical Beliefs
The metaphysical properties attributed to blue zircon extend beyond simple protection. It is believed to assist with meditation practices and improve organizational abilities. Astrologically, blue zircon is considered particularly beneficial for individuals born under the signs of Cancer, Gemini, Virgo, Capricorn, and Aquarius. In Indian astrological traditions, Libra and Taurus are also considered compatible with this gemstone.
The stone’s association with wisdom and confidence suggests a belief in its ability to empower the wearer, fostering a sense of inner strength and clarity. Its connection to restful sleep and dream clarity hints at a perceived ability to access and interpret subconscious insights.
Care and Cleaning
Due to its brittleness, blue zircon requires careful handling and protective settings. It is best suited for jewelry where the stone is less likely to experience impact, such as pendants or earrings. For rings and frequently worn pieces, protective settings that shield the edges and facets are strongly recommended. While resistant to scratching, the potential for chipping necessitates caution.
Specific cleaning instructions are not detailed in the provided sources, but given its hardness, gentle cleaning with warm, soapy water and a soft brush is likely appropriate. Avoid harsh chemicals or ultrasonic cleaners, which could potentially damage the stone.
Conclusion
Blue zircon stands as a captivating December birthstone, prized for its exceptional brilliance and fire. While often overshadowed by other blue gemstones, its unique optical properties and rich symbolism make it a compelling choice for jewelry enthusiasts. Its association with wisdom, creativity, and protection, coupled with its relatively good hardness, contribute to its enduring appeal. However, its brittleness necessitates careful handling and protective settings to ensure its longevity. Understanding these characteristics allows for a greater appreciation of this often misunderstood and truly beautiful gemstone.
