November is unique among the calendar months in possessing two recognized birthstones: citrine and yellow topaz. Both gemstones share a warm, inviting color palette, offering those born in November a choice reflecting the transition from autumn’s vibrant foliage to the approaching winter months. While topaz boasts a longer history and wider color range, citrine has gained prominence as a modern favorite, largely due to its affordability and appealing aesthetic. This article will delve into the history, geological origins, gemological properties, symbolism, and care of these captivating November birthstones.
History and Lore
The history of topaz extends back millennia. The ancient Greeks believed topaz possessed strength-giving properties, while Europeans from the 1300s to the 1600s considered it capable of warding off magic spells and dispelling anger. In India, wearing topaz above the heart was thought to ensure a long life, beauty, and intelligence. The very name “topaz” may originate from the Sanskrit word tapas, meaning “fire,” or from the Greek topazos.
Imperial topaz, a particularly prized golden hue, acquired its name from the 19th-century Russian monarchy, as significant deposits were initially found in Brazil but were highly valued by the Russian imperial family. Genuine Imperial topaz is a reddish-orange and highly saturated color, making it exceptionally rare – comprising less than half a percent of all gem-quality topaz. Any topaz labeled “Imperial” that has undergone treatment is not considered authentic.
Citrine’s history is more intertwined with that of amethyst and smoky quartz. For centuries, all yellow to brown quartz gems were often simply referred to as topaz. It wasn’t until advancements in gemology allowed for accurate identification that citrine was recognized as a distinct variety of quartz. Interestingly, much of the citrine available today isn’t naturally occurring; it’s created by heat-treating smoky quartz, a widely accepted practice within the gem industry.
The Jewelers of America likely introduced a second birthstone for November to expand options within the birthstone market, offering consumers a wider selection of gemstones.
Geological Formation and Sources
Topaz is formed in igneous rocks and is often found in alluvial deposits. Brazil is a significant source of topaz, producing a wide range of colors. Other sources include Russia, though historically important for Imperial topaz, and locations in Pakistan, Nigeria, and Sri Lanka.
Citrine, as a variety of quartz, forms in volcanic rocks. While natural citrine does occur, it is relatively rare. The majority of citrine on the market is produced by heat-treating smoky quartz, often at the mine site itself. Brazil is also a primary source for the smoky quartz that is subsequently transformed into citrine.
Gemological Properties
Both citrine and yellow topaz belong to different mineral groups but share a similar visual appeal. Topaz has a chemical formula of Al₂SiO₄(OH,F)₂, while citrine is SiO₂ (silicon dioxide), the same as amethyst and quartz.
Here’s a comparative overview of their key gemological properties:
| Property | Topaz | Citrine |
|---|---|---|
| Chemical Formula | Al₂SiO₄(OH,F)₂ | SiO₂ |
| Color | Yellow, orange, pink, blue, colorless | Yellow to orange |
| Hardness (Mohs) | 8 | 7 |
| Crystal System | Orthorhombic | Trigonal |
| Refractive Index | 1.606 – 1.627 | 1.544 – 1.553 |
| Specific Gravity | 3.49 – 3.57 | 2.65 |
Topaz is notably harder than citrine, registering an 8 on the Mohs scale compared to citrine’s 7. This difference in hardness affects their durability and susceptibility to scratching. Topaz also exhibits a wider range of colors, including blue (often achieved through irradiation and heating of colorless topaz), pink, and colorless varieties, in addition to the sought-after yellow and orange hues. Citrine’s color, stemming from trace amounts of iron, is limited to shades of yellow and orange.
It’s important to note that yellow topaz is often confused with citrine, a historical overlap stemming from the time before accurate gemological identification methods were available.
Symbolism and Metaphysical Beliefs
Both citrine and yellow topaz are associated with positive energies and are believed to bring fortune and warmth to the wearer. Citrine is often linked to prosperity, abundance, and success, while topaz is thought to promote clarity, intelligence, and long life.
November, as a month marking the transition into winter, is considered a time for introspection and welcoming truth. The warm colors of these birthstones serve as a reminder to stay connected to the light even as days grow shorter. Some associate November with a “warrior spirit” and powers of protection, further enhancing the symbolic significance of these gems.
Care and Cleaning
Due to its greater hardness, topaz is generally more durable than citrine. However, both gemstones require careful handling to avoid damage. Topaz can be susceptible to chipping if subjected to a sharp blow, while citrine, being less hard, is more prone to scratches.
Both gemstones can be cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can potentially damage the stones. It is also advisable to remove jewelry containing these gemstones before engaging in strenuous activities to prevent scratches or impacts.
Conclusion
Citrine and yellow topaz represent the vibrant spirit of November. While topaz boasts a rich history and diverse color palette, citrine offers an accessible and appealing alternative. Both gemstones are believed to possess positive energies, symbolizing prosperity, warmth, and clarity. Whether chosen for their beauty, historical significance, or perceived metaphysical properties, these golden hues provide a fitting tribute to those born in the eleventh month of the year.
