June boasts not one, but three recognized birthstones: moonstone, pearl, and alexandrite. While traditionally each month was assigned a single gemstone, the list has expanded over time, with additions made in 1952 and 2002, and again in 2016. These three gems each possess unique histories, geological origins, and aesthetic qualities, making June particularly rich in gemstone symbolism. This article will explore the origins, properties, and significance of these captivating stones.
History and Lore
The association of gemstones with specific months dates back to ancient times, rooted in astrological beliefs and the perceived magical properties of these minerals. These “astral stones” were thought to connect individuals to the energies of their astrological sign, potentially awakening hidden powers or offering healing and protection. The practice of assigning gemstones to months has evolved over centuries, with ancient, traditional, and modern lists coexisting today.
Pearls hold a particularly long and esteemed history. Ancient Egyptians valued pearls above all other precious stones, and a necklace believed to be from a Persian princess dating back to 520 B.C. remains the oldest known pearl necklace. The word “pearl” itself originates from the Latin word “pirum,” meaning “pear,” a reference to the gem’s characteristic shape.
Moonstone’s history is interwoven with mythology. Hindu tradition claims the stone is formed from solidified moonbeams, while both Roman and Greek cultures linked it to their lunar deities. Throughout history, moonstone has been associated with love, passion, and fertility, believed to bring good luck to its wearer.
Alexandrite, the most recent addition to June’s birthstone family, has a comparatively short but compelling history. It was first discovered in the Ural Mountains of Russia during the reign of Czar Alexander II, and the gem was named in his honor. The Russian alexandrites are noted for their high quality, large carat size, and aesthetic beauty.
Geological Formation and Sources
Each of these June birthstones originates through distinct geological processes. Pearls are unique among gemstones as they are organic, formed within living sea creatures – oysters. They are created as a defense mechanism against irritants, forming layers of calcium carbonate around a foreign object.
Moonstone belongs to the feldspar group of minerals and is renowned for its adularescence, the shimmering light that appears to billow across the stone. This effect is caused by light scattering between microscopic layers within the gem. Moonstone can be found in various locations worldwide, including the United States (New Mexico, North Carolina, and Virginia), India, Sri Lanka, Brazil, Madagascar, Myanmar, and Tanzania. India and Sri Lanka are considered the most important sources for high-quality moonstone.
Alexandrite is a form of chrysoberyl, a mineral formed in the Earth’s crust. Its remarkable characteristic is its ability to change color depending on the light source – appearing green in daylight and red in incandescent light. The original and highest quality alexandrite specimens were discovered in the Ural Mountains of Russia.
Gemological Properties
Each of these gemstones possesses unique gemological properties that contribute to its beauty and value.
Moonstone registers between 6 and 6.5 on the Mohs scale of hardness, making it relatively soft and susceptible to scratches and damage. It exhibits a pearly luster and is often colorless, though it can also display hues of peach, gray, or green. The most prized moonstones exhibit a blue sheen against a colorless background. Its structure is characterized by visible layers, which can be used to distinguish natural moonstones from synthetic versions.
Pearl is also relatively soft, with a hardness of around 2.5 to 4.5 on the Mohs scale. Unlike most gemstones, pearls do not require faceting or polishing to reveal their natural beauty. Ideal pearls are perfectly round and smooth, though other shapes are also common. Pearls are composed of calcium carbonate and are formed within the soft tissue of a living mollusk.
Alexandrite, with a hardness of 8.5 on the Mohs scale, is significantly more durable than moonstone or pearl. It is a variety of chrysoberyl and is known for its pleochroism – the ability to display different colors when viewed from different angles – and its dramatic color change.
Here's a table summarizing the key properties:
| Gemstone | Chemical Composition | Hardness (Mohs) | Luster | Key Characteristic |
|---|---|---|---|---|
| Moonstone | Feldspar | 6-6.5 | Pearly | Adularescence (shimmering light) |
| Pearl | Calcium Carbonate | 2.5-4.5 | Nacreous | Organic gem formed within a mollusk |
| Alexandrite | Chrysoberyl | 8.5 | Vitreous | Dramatic color change |
Symbolism and Metaphysical Beliefs
Throughout history, each of these June birthstones has been attributed with specific meanings and powers. Moonstone is often associated with love, passion, and fertility, believed to bring good luck. Alexandrite is said to bring joy, good luck, and improve self-esteem. Pearls have long been symbols of purity, innocence, and wisdom.
The belief in the metaphysical properties of gemstones is deeply rooted in ancient traditions. Some believe that these stones carry the ability to affect healing, protective abilities, and benefit the mind, body, and soul. Others believe that the stones’ energies are linked to planetary influences, impacting an individual’s qualities and destiny.
Care and Cleaning
Due to their differing hardness levels, each of these gemstones requires specific care to maintain its beauty. Moonstone, being relatively soft, is prone to cracking and cleaving, and should not be exposed to high heat. Ultrasonic and steam cleaners should be avoided. The recommended cleaning method is warm, soapy water with a soft brush. Pearls also require gentle care. Avoid harsh chemicals, abrasive cleaners, and ultrasonic cleaners. Clean pearls with a soft cloth and mild soap. Alexandrite, being the most durable of the three, can withstand more rigorous cleaning, but it is still advisable to avoid harsh chemicals and ultrasonic cleaners. Warm, soapy water and a soft brush are the safest cleaning method.
Natural vs. Synthetic
While natural moonstones can be identified by their layered structure and characteristic blue lustrous gleam, synthetic moonstones are also available. Similarly, while natural pearls were historically highly prized, cultured pearls are now widely available and often more affordable. Alexandrite, due to its rarity, is also subject to synthetic production.
Applications of June Birthstones
Traditionally, birthstones were used to manifest certain powers or attributes. However, in modern times, they are primarily valued for their beauty and symbolic meaning. June birthstones are popular gifts, expressing sentiments of love and beauty, and are fitting mementos for those born in June. Moonstone and pearl rings, in particular, are favored for their perceived medicinal benefits and mystical charm. Alexandrite, with its unique color-changing property, is used in a range of jewelry pieces, from rings to pendants.
Conclusion
Moonstone, pearl, and alexandrite represent a diverse and captivating collection of June birthstones. From the ethereal shimmer of moonstone to the timeless elegance of pearls and the remarkable color change of alexandrite, each gem offers a unique blend of beauty, history, and symbolism. Whether one believes in their metaphysical properties or simply appreciates their aesthetic appeal, these gemstones continue to fascinate and inspire. Their enduring popularity as birthstones and jewelry pieces underscores their lasting significance in both cultural traditions and modern adornment.
