November is unique among the calendar months in possessing two recognized birthstones: topaz and citrine. While both gemstones offer warm, inviting colours, their histories, geological origins, and symbolic meanings are distinct. For centuries, these stones have been valued for their beauty and believed to bestow various benefits upon their wearers. This article will explore the fascinating world of November’s birthstones, detailing their properties, historical significance, and enduring appeal.
History and Lore
The history of topaz and citrine is intertwined, particularly regarding their identification. Until the 1930s, yellow to brownish-orange gemstones were often collectively referred to as topaz. It wasn’t until advancements in gemological science allowed for accurate mineral identification that the distinction between topaz and citrine became clear. Prior to this, the pale-yellow hue of citrine was easily mistaken for yellow topaz.
Topaz boasts a long and storied past, with references appearing in ancient Greek texts. The ancient Greeks believed topaz granted strength to those who wore it. Europeans, from the 1300s to the 1600s, held the belief that topaz could ward off magic spells and dispel anger. In India, wearing topaz above the heart was thought to ensure a long life, beauty, and intelligence.
Citrine’s history is somewhat less documented independently, often overshadowed by its association with topaz. However, both stones have been valued across cultures for their perceived positive energies. The addition of citrine as a November birthstone is attributed to a desire by the Jewelers of America to expand the options available in the birthstone market.
Geological Formation and Sources
Topaz is a silicate mineral containing aluminum and fluorine, forming in igneous rocks. It crystallizes in prismatic crystals and occurs in a wide range of colours, including colorless, light blue, yellow, orange, pink, violet, brown, and, very rarely, red. Imperial topaz, a prized orange with pink undertones, is considered the most valuable colour variety. The vast majority of blue topaz available today is created through irradiation and heating of colorless topaz. A process called “Mystic Topaz” creates a rainbow effect by coating colorless topaz with a thin artificial film.
Citrine, a variety of quartz, derives its yellow to orange hues from iron impurities. A notable source of citrine is the Anahí mine, which uniquely produces both amethyst and citrine within the same crystal, resulting in a gem known as ametrine. Citrine from the Anahí mine typically ranges in colour from orange-yellow to brownish/greenish yellow.
Gemological Properties
Both topaz and citrine offer durability and aesthetic appeal, making them suitable for various jewellery applications. However, their gemological properties differ significantly.
Topaz:
- Chemical Formula: Al₂SiO₄(OH,F)₂
- Hardness (Mohs Scale): 8
- Crystal System: Orthorhombic
- Refractive Index: 1.606 – 1.627
- Specific Gravity: 3.49 – 3.57
- Colour: Colourless, blue, yellow, orange, pink, violet, brown, red (rare)
Citrine:
- Chemical Formula: SiO₂ (Silicon Dioxide)
- Hardness (Mohs Scale): 7
- Crystal System: Trigonal
- Refractive Index: 1.545 – 1.553
- Specific Gravity: 2.65
- Colour: Yellow to orange, brownish/greenish yellow
The Mohs hardness scale demonstrates that citrine, at 7, is slightly less durable than topaz, which registers at 8. This means topaz is more resistant to scratching and is often favoured for rings. Both gemstones are generally durable enough for normal wear and care.
Symbolism and Metaphysical Beliefs
Throughout history, both topaz and citrine have been imbued with symbolic meaning. Topaz is associated with strength, honour, wisdom, and a sense of calm and balance. Blue topaz, in particular, is often chosen for its relaxing colour and dazzling sparkle.
Citrine is often linked to prosperity, abundance, and positive energy. Its warm, sunny hues are seen as a reminder of light even during darker times. The association with November, a month marking the transition into winter in the Northern Hemisphere, reinforces this symbolism. Scorpios, those born under the zodiac sign associated with November, can choose either citrine or topaz as their birthstone.
Care and Cleaning
Maintaining the beauty of topaz and citrine is relatively straightforward. Citrine, with its good toughness, can be safely cleaned with warm, soapy water. Ultrasonic cleaning is generally acceptable, but steam cleaning should be avoided as high heat could potentially cause cracking.
Topaz, being slightly more brittle, also benefits from gentle cleaning with warm, soapy water. While durable, it’s advisable to avoid harsh chemicals or abrasive cleaners. Both gemstones should be stored separately from other jewellery to prevent scratching.
Popular Jewellery Choices
Topaz and citrine are versatile gemstones used in a wide range of jewellery designs. Popular choices include blue topaz rings, bracelets featuring both topaz and other gemstones, and pendants showcasing cushion-cut blue topaz with diamond accents. The affordability and availability of both stones make them accessible options for creating stunning and meaningful pieces.
