The month of November is uniquely distinguished in the world of birthstones by having two official gemstones: topaz and citrine. Both stones are celebrated for their vibrant colors, symbolic significance, and rich historical associations. Together, they embody the warmth and transformation associated with the late autumn season. This article delves into the fascinating duality of November’s birthstones, exploring their geological properties, historical and cultural significance, and practical considerations for care and selection.
Introduction
November is the only month with two official birthstones: topaz and citrine. This distinction allows individuals born in November a greater range of choice when it comes to selecting a gemstone that reflects their personal style and budget. While topaz has long been considered the traditional November birthstone, citrine was added to the list in 1952 due to its affordability and widespread availability. Both stones share a warm color palette and are often associated with themes of strength, vitality, and joy.
This article explores the unique qualities of topaz and citrine, drawing from historical, scientific, and cultural sources. It will cover the origins of these stones as birthstones, their physical and chemical properties, their symbolic meanings across cultures, and practical guidance on how to care for and select these gems.
History and Lore
The Origins of November Birthstones
The concept of birthstones can be traced back to the 1st and 5th centuries, when lists of twelve gemstones were derived from biblical references. At that time, topaz was designated as the birthstone for November. The practice of wearing birthstones became popular in the 16th century, but it wasn’t until the 19th century that the modern system was formalized.
In 1870, Tiffany & Co. released a pamphlet titled Gregorian Birthstone Poems, which included topaz for November. The National Association of Jewellers (now Jewellers of America) and the National Association of Goldsmiths both listed topaz as the November birthstone in 1912 and 1937, respectively. However, in 1952, the Jewelry Industry Council of America updated the list, adding citrine as an alternative to topaz, likely due to its greater availability and lower cost.
The UK still recognizes topaz alone as the November birthstone, while the US officially lists both topaz and citrine. This dual designation allows for a broader appeal and flexibility in jewelry design, catering to different tastes and budgets.
Geological Formation and Sources
Topaz: A Durable and Versatile Gemstone
Topaz is a silicate mineral composed of aluminum silicate fluoride hydroxide, with the chemical formula Al₂SiO₄(F,OH)₂. It is known for its exceptional hardness, ranking 8 on the Mohs scale, making it suitable for everyday wear in jewelry. Topaz forms in hydrothermal veins and pegmatites, which are igneous rocks that cool slowly, allowing for the formation of large crystals.
Major sources of topaz include:
- Brazil – Known for producing high-quality topaz in a wide range of colors.
- Russia – A historical source, particularly for the rare imperial topaz, which is prized for its golden-orange to reddish hues.
- Mexico – Produces topaz in various colors, including the popular blue topaz.
- Sri Lanka – Known for its yellow and brown topaz.
Topaz is also found in Myanmar, Nigeria, and the United States. The gem is often treated to enhance its color, with blue topaz being one of the most popular varieties. This color is typically achieved through irradiation and heat treatment.
Citrine: A Warm and Abundant Stone
Citrine is a variety of quartz, with the chemical formula SiO₂. It is known for its golden to orange-yellow coloration, which is caused by trace amounts of iron within the crystal structure. Citrine is relatively abundant, which contributes to its affordability and widespread use in jewelry.
The most significant sources of citrine are:
- Brazil – The largest and most well-known producer of citrine.
- Uruguay – Known for producing Madeira citrine, which ranges from deep golden to reddish-brown.
- Russia – A historical source, particularly for citrine used in Russian imperial jewelry.
- Spain and France – Smaller producers of high-quality citrine.
Citrine is also found in Nigeria, Madagascar, and the United States. It is often used as a more affordable alternative to yellow topaz and is popular in both jewelry and decorative objects.

Care and Cleaning
Topaz
Due to its high hardness (8 on the Mohs scale), topaz is a very durable gemstone. However, it can still be chipped or fractured if subjected to hard impacts, especially along its cleavage planes. Topaz is also sensitive to heat and radiation, so care should be taken when storing or cleaning it.
Cleaning Tips: - Avoid ultrasonic cleaners, as they can cause damage to the stone. - Use a soft brush and warm, soapy water to gently clean the gemstone. - Store topaz separately from other gemstones to prevent scratches or damage. - Avoid exposure to extreme temperatures, especially when treating the stone for color enhancement.
Citrine
Citrine is a very stable gemstone and is relatively easy to care for. Its hardness of 7 makes it suitable for everyday wear, but it can still be chipped if dropped on a hard surface.
Cleaning Tips: - Use a soft brush and warm, soapy water to clean citrine. - Ultrasonic cleaners can be used, but only if the stone is untreated. - Avoid steam cleaning, as it can cause the stone to fog or lose luster. - Store citrine separately from other gemstones to prevent scratches.
