December boasts a selection of captivating blue gemstones, and among them, Blue Topaz stands out as a popular and enchanting birthstone choice. While traditionally, Turquoise, Tanzanite, and Blue Zircon have been associated with this month, Blue Topaz has gained prominence as a modern alternative, particularly in the United States. This article will explore the history, gemological properties, symbolism, and care of Blue Topaz, offering a comprehensive overview of this beautiful December birthstone.
History and Lore
The very name “topaz” originates from the Sanskrit word for “fire,” hinting at the gem’s long-held association with warmth and energy. Throughout history, birthstones have been valued for their symbolism and believed to bestow specific attributes upon those born in their corresponding month. The concept of birthstones traces back to ancient civilizations – Egypt, Greece, and Rome – where gemstones were thought to possess mystical and healing properties. Blue Topaz, as a December birthstone, adds a personal touch to jewelry and gifts, enhancing individuality and uniqueness.
While the historical origins of specifically blue topaz as a December birthstone are more recent, the gem itself has been prized for centuries. The assignment of specific gemstones to months evolved over time, with modern lists being formalized in the 20th century. The Jewelers of America officially recognized Blue Topaz as a December birthstone in 2002, solidifying its place alongside the traditional choices.
Geological Formation and Sources
Blue Topaz is a silicate mineral composed of aluminum and fluorine. It possesses a glass-like luster and exhibits a distinct cleavage, meaning it can be somewhat delicate despite its relatively good hardness. The gem’s captivating color and radiant sparkle contribute to its popularity in a wide range of jewelry designs.
It is important to note that most commercially available blue topaz is not naturally occurring. The vibrant blue hues seen in the market are typically achieved through irradiation of naturally colorless topaz. This treatment is a widely accepted practice in the gem industry and does not diminish the gem’s beauty or value, though natural blue topaz is rarer and can command a higher price.
The sources of topaz are varied, but specific locations for blue topaz production are not detailed in the provided materials. However, the materials indicate a global appreciation for the gem, with references to stones exhibited in museums like the UK Natural History Museum.
Gemological Properties
Blue Topaz exhibits a range of blue shades, from pale, almost translucent hues to rich, vibrant aqua tones and deep, inky blues. These variations have led to the categorization of different blue topaz varieties:
- London Blue Topaz: This variety features a deep, inky blue color, highly prized by collectors. The name originates from a large blue topaz stone exhibited at the UK Natural History Museum.
- Swiss Blue Topaz: Displaying a vibrant, medium-light blue, Swiss Blue Topaz immediately catches the eye.
- Sky Blue Topaz: This variety offers a light aqua color, reminiscent of clear blue skies.
The chemical formula for Blue Topaz is Al2SiO4(F,OH)4, indicating its strong chemical bonding, which contributes to its hardness. On the Mohs scale of hardness, Blue Topaz registers an 8, making it relatively durable and suitable for everyday wear.

Symbolism and Metaphysical Beliefs
Blue Topaz is often associated with calmness and peace, believed to bring tranquility to its wearer. It is also linked to loyalty and love, making it a meaningful gift for expressing affection. Historically, gemstones were believed to have mystical and healing properties, and while these beliefs are not scientifically proven, they continue to resonate with many.
Beyond its association with December, Blue Topaz also has connections to zodiac signs. Ancient astrologers assigned gemstones to planets, believing them to reflect the influence of the stars on human personalities. While originally, zodiac stones and birthstones were synonymous, they have diverged over time, with zodiac birthstones often being semi-precious gems. According to one chart, Blue Topaz is not directly listed as a primary zodiac birthstone, but its association with the color blue and its calming properties may appeal to individuals seeking a gem aligned with their astrological sign.
Care and Cleaning
Due to its distinct cleavage, Blue Topaz is somewhat delicate and requires careful handling. While its hardness of 8 makes it resistant to scratching, a sharp blow could cause it to chip or fracture. Regular cleaning can maintain its brilliance. The materials do not provide specific cleaning instructions, but given its hardness, gentle cleaning with warm, soapy water and a soft brush is generally recommended. Avoid harsh chemicals or ultrasonic cleaners, as these could potentially damage the gem.
Conclusion
Blue Topaz has secured its place as a beloved December birthstone, offering a stunning alternative to the traditional Turquoise, Tanzanite, and Blue Zircon. Its captivating range of blue hues, from the deep inky shades of London Blue to the vibrant lightness of Swiss and Sky Blue varieties, appeals to a wide range of tastes. Beyond its aesthetic beauty, Blue Topaz is associated with qualities of peace, loyalty, and love, making it a meaningful and cherished gemstone for those born in December. Its relatively good hardness and availability make it a versatile choice for various jewelry designs, ensuring its continued popularity for years to come.
