Why do some months have multiple birthstones?
The tradition of birthstones has evolved significantly over time, reflecting both cultural changes and developments in the gemstone industry. While some months maintain a singular traditional gemstone, others have expanded to include multiple options, offering greater flexibility and choice for modern jewelry enthusiasts. This evolution stems from factors such as gemstone availability and the discovery of new stones that complement traditional choices.
Over the past century, official birthstones have been updated to address several practical concerns, including the scarcity of certain gems and the need for more affordable options. For example, when natural pearls became increasingly rare and expensive, alexandrite was added as an alternative June birthstone.
These updates also reflect exciting developments in the gemstone world, such as the discovery of new stones. (For example, tanzanite was discovered in 1967 and joined December’s birthstone lineup.) The addition of multiple birthstones gives people more choices to fit their lifestyle and budget. Some additions, like tourmaline for October, provide more durable alternatives for everyday wear, while others offer similar beauty at different price points, making birthstone jewelry more accessible to everyone.
What Months Have Two Birthstones?
November, June and October each have two birthstone options:
June features:
- Pearls – formed naturally in oysters and mussels
- Alexandrite – a rare gem that changes color under different lighting, appearing green in daylight and red under artificial light
October offers:
- Opal – known for displaying multiple colors within the stone
- Tourmaline – available in many colors and typically more durable than opal for daily wear
And November birthstones include:
- Citrine – a golden yellow quartz that ranges from pale lemon to deep amber tones
- Topaz – traditionally associated with blue hues, but naturally occurs in many colors including the prized imperial topaz with its sunset orange-pink glow
What Months Have Three Birthstones?
August is the only month with three birthstone choices:
- Peridot – a natural bright green stone
- Spinel – available in multiple colors and often more affordable than similar-looking gems
- Sardonyx – features distinctive red and white bands and is the most budget-friendly option
What Months Have Four Birthstones?
December has the most birthstone options with four choices:
- Tanzanite – a blue-violet stone discovered in the 1960s
- Zircon – one of the oldest minerals on Earth
- Turquoise – a blue-green stone with a long history in jewelry
- Blue Topaz – ranges from light to deep blue and typically costs less than the other options
These multiple birthstone options let people choose gems that fit both their personal style and budget. Each stone meets different needs – some are more durable for everyday wear, while others might be saved for special occasions. Having multiple options makes birthstone jewelry more accessible and wearable for all of life’s occasions.
