Labradorite is a captivating gemstone renowned for its remarkable play of color, known as labradorescence. While not traditionally among the most widely recognized birthstones, it holds a significant place as an alternative November birthstone and, notably, as a birthstone option for June, particularly associated with those born under the sign of Gemini. This feldspar mineral, with its shifting hues and intriguing lore, has fascinated people for centuries, finding use not only in jewelry but also in industrial applications and spiritual practices.
History and Lore
The story of labradorite begins with its discovery around 1770 by Moravian missionaries on the Isle of Paul, off the coast of Labrador, Canada. It was this location that lent the stone its name. However, the stone’s use and appreciation predate its formal discovery, with evidence suggesting its utilization in various cultures for centuries.
Labradorite’s striking appearance quickly captured the imagination of people. Beyond its aesthetic appeal, the stone became imbued with rich folklore. Indigenous peoples of Labrador believed the stone contained the Aurora Borealis, released when a warrior struck the rock with his spear. This belief speaks to the stone’s ethereal quality and the mesmerizing play of light within it.
More recently, labradorite has gained prominence in metaphysical circles, where it is valued for its purported healing properties and connection to intuition and spiritual awareness. It is considered a stone of transformation, believed to help individuals navigate change and reveal hidden truths.
Geological Formation and Sources
Labradorite belongs to the plagioclase feldspar group, a series of solid solution minerals composed of sodium, calcium, aluminum, and silicon. Specifically, it is an anorthite plagioclase feldspar, with a composition ranging from 30-70 percent anorthite and 30-50 percent albite. The stone forms in massive structures, and its characteristic labradorescence arises from the internal structure of the mineral, where layers of varying compositions refract light.
While originally discovered in Labrador, Canada, labradorite is now found in various locations worldwide. Significant sources include the United States, Canada, Madagascar, Russia, Norway, and the United Kingdom. A particularly vibrant variety, known as Spectrolite, is sourced from Finland, displaying the full spectrum of colors within its structure. Oregon sunstone, a type of labradorite, is also notable for its aventurescence, a metallic glittering effect.
Gemological Properties
Labradorite is a semi-precious gemstone, distinct from the “precious” stones of diamond, ruby, sapphire, and emerald. On the Mohs scale of hardness, it registers between 6 and 6.5, making it relatively soft and susceptible to scratching. This moderate hardness requires careful handling and storage to maintain its polish and brilliance.
The stone typically appears white, gray, yellow, or colorless in its base form. However, it is the labradorescence – the iridescent play of color – that defines labradorite’s beauty. This optical phenomenon results from light interference within the layered structure of the mineral. Colors commonly observed include blue, green, yellow, orange, red, and even purple. The intensity and range of colors can vary significantly, with stones exhibiting a high degree of labradorescence being particularly prized. Spectrolite, in particular, is known for displaying the entire spectrum of colors.
The composition of labradorite is complex, with varying amounts of sodium and calcium. Its chemical formula reflects this, being a solid solution of anorthite (calcium aluminum silicate) and albite (sodium aluminum silicate). While not all labradorite exhibits labradorescence, those that do are highly sought after for their unique and captivating appearance.
Here's a table summarizing key gemological properties:

| Luster | Vitreous |
| Optical Effect | Labradorescence |
| Common Colors | Gray, White, Yellow |
| Iridescent Colors | Blue, Green, Orange, Red, Purple |
Symbolism and Metaphysical Beliefs
Throughout history and across cultures, labradorite has been attributed with various symbolic meanings and metaphysical properties. In astrology, it is associated with the zodiac sign of Cancer, and Spectrolite is considered lucky for Scorpio, Sagittarius, and Leo. Some astrologers also recommend wearing labradorite during significant Venus phases.
Labradorite is often regarded as a stone of protection, shielding against negativity and promoting strength in the face of change. It is believed to raise consciousness, reveal hidden truths, and enhance intuition. Many believe it assists individuals undergoing transitions, providing stability and encouraging self-discovery.
The stone’s connection to the Aurora Borealis further reinforces its association with spiritual enlightenment and the unveiling of inner wisdom. It is considered a powerful tool for meditation, facilitating inner peace and spiritual connection.
Care and Cleaning
Due to its moderate hardness, labradorite requires careful handling and cleaning. To maintain its brilliance, it should be cleaned with mild soap, warm water, and a soft brush. Rinse thoroughly and dry with a microfiber cloth. It is important to store labradorite jewelry separately from other gemstones to prevent scratching.
Avoid exposing labradorite to harsh chemicals or abrasive cleaners, as these can damage the stone’s surface and diminish its labradorescence. Remove jewelry containing labradorite before engaging in activities that could expose it to impact or chemicals, such as cleaning or applying makeup.
Conclusion
Labradorite is a truly remarkable gemstone, captivating with its ethereal beauty and rich history. From its origins in the rugged landscapes of Labrador, Canada, to its current status as a sought-after gemstone and spiritual tool, labradorite continues to inspire and enchant. Whether appreciated for its stunning play of color, its connection to ancient lore, or its purported metaphysical properties, labradorite remains a significant and cherished stone, particularly for those born in June or November, and for anyone seeking a touch of magic and transformation in their lives.
