History and Lore: From Ancient Seas to Imperial Russia
The story of the June birthstones is one of evolution, reflecting changing tastes, discoveries, and the expansion of global trade. The path to the current selection of three stones for June—Pearl, Moonstone, and Alexandrite—is rooted in centuries of tradition and adaptation.
The Primacy of the Pearl Pearl is the original and most enduring birthstone for the month of June. Its history is intertwined with human civilization for millennia. As organic gems formed within the soft tissue of mollusks like oysters and mussels, pearls have been coveted since antiquity. The sources describe a process where an irritant, such as a grain of sand, enters the mollusk, which then secretes layers of nacre—a combination of calcium carbonate and the protein conchiolin—to coat the intruder. This biological process results in the lustrous, smooth orbs that have been treasured across cultures. For much of history, pearls were accessible only to royalty and the extremely wealthy due to their rarity and the difficulty of harvesting them from the wild. Their association with purity, wisdom, and serenity made them symbols of status and spiritual depth, solidifying their place as the premier June birthstone in early birthstone lists.
The Introduction of Moonstone and Alexandrite The birthstone list for June expanded over time, a change driven by factors such as the availability of gems and the desire for variety. Moonstone, a mystical gem associated with lunar energy, was adopted into more modern lists, particularly gaining popularity in Europe. Its milky white appearance with a bluish shimmer, and its lore connecting it to feminine energy, intuition, and new beginnings, offered a different kind of allure compared to the oceanic pearl.
The most significant modern addition was Alexandrite, which joined the list in the 1950s. Its story is more recent and geographically specific. Alexandrite was first discovered in the Ural Mountains of Russia in the early 1830s. The gem was named after the future Tsar Alexander II, and its remarkable color-changing property—appearing green in daylight and reddish-purple in incandescent light—was said to mirror the imperial colors of old Russia. This unique characteristic and its rarity made it an instant favorite among Russian aristocracy. Its official inclusion as a June birthstone in the mid-20th century acknowledged its distinct beauty and symbolic resonance, providing a modern, transformative alternative to the traditional pearl.
The current standardization, which lists Pearl, Moonstone, and Alexandrite as the three official birthstones for June, was largely solidified by organizations like the American National Retail Jewelers Association (now Jewelers of America) in the early 20th century, with Alexandrite's addition coming later. This evolution ensures that individuals born in June, including those on the 13th, have a diverse palette of gems to choose from, each with its own unique history and meaning.
Geological Formation and Sources
The genesis of a gemstone defines its character, and the origins of Pearl and Alexandrite could not be more different. One is born of the living sea, while the other crystallizes deep within the Earth's crust.
Pearl: An Organic Masterpiece Pearls are unique among gemstones as they are organic, not mineral. They are formed within the mantle tissue of living mollusks, primarily oysters and mussels. The formation process is a natural defense mechanism. When an irritant lodges itself within the mollusk's soft tissue, the animal secretes layer upon layer of nacre around it. Nacre is composed of microscopic crystals of aragonite (a form of calcium carbonate) bound together by the organic protein conchiolin. Over several years, these concentric layers build up to form a pearl. The finest natural pearls have historically come from the Persian Gulf, the Red Sea, and the waters around Sri Lanka (formerly Ceylon). Today, while natural pearls are exceedingly rare and command high prices, the vast majority of pearls on the market are cultured pearls, where a human intentionally introduces an irritant to stimulate nacre production. This method, developed in the early 20th century, makes pearls more accessible while still retaining their natural beauty.
Alexandrite: A Rare Mineralogical Marvel In stark contrast, Alexandrite is a mineral, specifically a variety of chrysoberyl. Its chemical formula is BeAl₂O₄, and it is the presence of trace amounts of chromium that gives Alexandrite its signature color-changing ability. The chromium ions substitute for aluminum in the crystal lattice, absorbing light in the yellow and blue parts of the spectrum, which allows the green and red wavelengths to be seen. This phenomenon is known as the "alexandrite effect." The finest Alexandrite was originally discovered in the Ural Mountains of Russia, in the emerald-bearing deposits near the Tokovaya River. The Russian material, especially from the 19th century, is considered the benchmark for quality, displaying a vivid green in daylight and a rich raspberry red under incandescent light. While the original Russian deposits are largely depleted, new sources have been found. Today, significant deposits of Alexandrite are located in Brazil, particularly in the states of Minas Gerais and Bahia. Other sources include Sri Lanka, India, and parts of Africa. However, fine-quality Alexandrite with a strong color change remains exceptionally rare and valuable.
Gemological Properties
Understanding the physical and chemical properties of a gemstone is crucial for identification, valuation, and care. The following table summarizes the key gemological characteristics of Pearl and Alexandrite, based on the information provided in the sources.
| Property | Pearl | Alexandrite |
|---|---|---|
| Mineral Family | Organic (Biogenic) | Chrysoberyl (Mineral) |
| Chemical Composition | Calcium Carbonate (Aragonite) & Conchiolin | Beryllium Aluminum Oxide (BeAl₂O₄) with Chromium |
| Crystal System | Amorphous (Non-crystalline) | Orthorhombic |
| Hardness (Mohs Scale) | 2.5 - 4.5 | 8.5 |
| Luster | Subvitreous to Vitreous (Nacreous) | Vitreous |
| Refractive Index | 1.490 - 1.685 | 1.746 - 1.755 |
| Color | White, Cream, Pink, Black, Golden | Green in Daylight, Reddish-Purple in Incandescent Light |

| Special Property | Nacreous Luster, Organic Origin | Strong Alexandrite Effect (Color Change) |
Pearl's Delicate Nature Pearls are notably soft compared to most gemstones, with a hardness ranging from 2.5 to 4.5 on the Mohs scale. This low hardness makes them susceptible to scratching and abrasion from everyday materials like dust (which contains quartz, hardness 7). Their structure, composed of alternating layers of aragonite and conchiolin, gives them their characteristic luster but also makes them vulnerable to acids, chemicals, and prolonged exposure to perspiration. The color of pearls varies widely, from classic white and cream to pink, black, and golden, influenced by the type of mollusk and the environment in which they are formed.
Alexandrite's Exceptional Durability and Effect Alexandrite is a very hard and durable gemstone, with a Mohs hardness of 8.5. This makes it suitable for all types of jewelry, including rings and bracelets that are subject to daily wear, without significant risk of scratching. Its most defining property is the color change, a result of its unique light absorption properties. The quality of an Alexandrite is judged primarily by the intensity and attractiveness of its color change. The ideal Alexandrite displays a vivid emerald green in natural daylight (which is rich in blue wavelengths) and a distinct raspberry red or purplish-red in incandescent light (which is rich in red wavelengths). The clarity of Alexandrite is also important; while inclusions are common, the finest stones are eye-clean. Its refractive index is relatively high, contributing to its brilliance when well-cut.
Symbolism and Metaphysical Beliefs
Beyond their physical beauty, Pearl and Alexandrite are steeped in symbolism and metaphysical lore that adds layers of meaning to their wear.
Pearl: The Stone of Purity and Wisdom Pearls have long been symbols of purity, innocence, and integrity. In many cultures, they are associated with the moon and are believed to embody serene, feminine energy. Metaphysical traditions attribute to pearls the ability to calm the mind, reduce stress, and attract luck and protection. They are often linked to wisdom gained through experience and are considered stones of sincerity and spiritual awareness. For those born on June 13th, wearing a pearl is thought to foster a sense of calm and centeredness, serving as a reminder of inner purity and the beauty that can emerge from life's irritants.
Alexandrite: The Stone of Transformation and Balance Alexandrite’s symbolism is directly tied to its dramatic color change. It represents adaptability, balance, and transformation. The stone's ability to appear in two completely different guises is seen as a metaphor for life's duality and the importance of embracing change. In metaphysical practices, Alexandrite is believed to bring joy, good fortune, and prosperity to its wearer. It is associated with the balancing of energies and is thought to support personal growth and the ability to navigate life's transitions with grace. As a modern birthstone, Alexandrite offers a powerful symbol of transformation for those born on June 13th, encouraging them to adapt and thrive.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone. The contrasting properties of Pearl and Alexandrite necessitate very different maintenance routines.
Caring for Pearls Due to their low hardness and organic composition, pearls require gentle handling. They should be the last item you put on (after applying cosmetics, perfume, and hairspray) and the first item you take off. To clean pearls, simply wipe them with a soft, damp cloth after wearing to remove oils and perspiration. Avoid submerging them in water, especially if they are strung, as the string can weaken. Never use ultrasonic cleaners, steam cleaners, or harsh chemicals like ammonia or bleach, as these can damage the nacre. Pearls should be stored separately from other jewelry to prevent scratches, ideally in a soft pouch or lined jewelry box.
Caring for Alexandrite Alexandrite's high hardness and durability make it much easier to care for. It can be safely cleaned using warm water, a mild dish soap, and a soft brush. Ultrasonic cleaners are generally safe for untreated Alexandrite, but caution is advised if the stone has been fracture-filled or has significant inclusions. As with all fine jewelry, it is wise to remove Alexandrite pieces before engaging in strenuous activities to avoid hard impacts, which, while unlikely to scratch, could potentially cause chipping along cleavage planes. Storing it separately is recommended to prevent it from scratching other softer gems.
