Pink tourmaline is a captivating gemstone celebrated for its diverse shades and increasing popularity as a birthstone. Officially recognized as an October birthstone in 1912, it offers a vibrant alternative to the traditional opal. This article delves into the history, geological origins, gemological properties, symbolism, and care of pink tourmaline, drawing exclusively from available sources.
History and Lore
Prior to the early 20th century, opal held exclusive association with the month of October. However, the American National Retail Jewelers Association, now known as Jewelers of America, sought to expand birthstone options, leading to the adoption of pink tourmaline. This decision was likely influenced by the gem’s growing availability due to significant discoveries in the late 19th and early 20th centuries, particularly in Brazil and Africa. The introduction of pink tourmaline provided a more durable and colorful choice for those seeking a gemstone representing their October birth.
Geological Formation and Sources
Tourmaline is not a single mineral but a group of closely related mineral species. Pink tourmaline, a variety within this group, is found in various locations worldwide. Primary mining regions include Brazil, Tanzania, Nigeria, Kenya, Madagascar, Mozambique, Malawi, and Namibia. Australia also produces opal, another October birthstone, with 95% of the world’s precious opal originating there. Pink quartz, also associated with October, is abundant in deposits found in Brazil, South Africa, India, and Madagascar, as well as Namibia, Mozambique, and Sri Lanka.
The formation of tourmaline involves complex geological processes, often occurring in pegmatites – igneous rocks formed during the final stages of magma cooling. These environments provide the necessary chemical elements and conditions for tourmaline crystals to develop.
Gemological Properties
Pink tourmaline exhibits a range of hues, from light pink to reddish-pink. Dealers often refer to red and pink tourmaline as rubellite. Color depth is considered more important than clarity, with saturated colors commanding the highest prices. The gem typically registers between 7 and 7.5 on the Mohs hardness scale, indicating good durability, though it is not as hard as pink sapphire.
Tourmaline crystals can grow to substantial sizes, making them suitable for larger jewelry pieces. Some specimens may exhibit inclusions that create attractive optical effects, such as a cat's eye (chatoyancy) or a star effect (asterism).

Symbolism and Metaphysical Beliefs
Pink gemstones, in general, are often associated with the heart chakra, believed to be the center of love, compassion, and emotional balance. Pink tourmaline, along with rose quartz and rhodonite, is thought to help balance and heal this chakra.
Specifically, pink tourmaline is said to symbolize friendship, compassion, self-love, and transformation. In crystal healing practices, it is believed to promote feelings of self-love and balance emotional health, releasing emotional blockages and harmonizing other chakras.
Pink Gemstone Varieties and Alternatives
While pink tourmaline is a prominent October birthstone, several other pink gemstones are available and hold significance. These include:

Care and Cleaning
Due to its moderate hardness (7-7.5 on the Mohs scale), pink tourmaline requires careful handling to avoid scratches and damage. It is advisable to remove jewelry containing pink tourmaline before engaging in strenuous activities or when exposed to harsh chemicals.
Cleaning can be performed with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and steam cleaners, as these may damage the gemstone. After cleaning, rinse thoroughly and dry with a soft cloth.
