June is unique among the months for offering not one, but three distinct birthstones: Pearl, Moonstone, and Alexandrite. This trio provides a diverse palette of colors, textures, and lore, making it one of the most versatile months for gemstone enthusiasts and jewelry buyers. While the pearl stands as the ancient and traditional choice, the addition of moonstone and alexandrite in modern lists reflects a broader understanding of gemstone rarity and symbolism. The beauty of the June birthstone lies in this diversity; from the organic luster of pearls to the celestial glow of moonstone and the dramatic color-changing properties of alexandrite, these gems capture a wide spectrum of aesthetic and spiritual preferences.
The visual identity of June's gems is remarkably varied. Pearls are celebrated for their soft, creamy whites and subtle pinks, embodying classic elegance. Moonstone shimmers with a mystical blue or white adularescence, often associated with ethereal beauty. Alexandrite presents a scientific marvel, appearing green in daylight and shifting to a reddish hue under incandescent light. This dynamic range ensures that those born in June have access to a gemstone that matches not only their style but also the energetic qualities they wish to embody. Whether drawn to the purity of pearl, the emotional balance of moonstone, or the transformative power of alexandrite, the June-born have a rich selection of treasures to choose from.
History and Lore: From Ancient Tradition to Modern Discovery
The history of June's birthstones spans millennia, beginning with the pearl, the oldest of the three. Historically, pearls have been revered across numerous cultures for their natural beauty and rarity. They are unique among gems because they are formed within living creatures rather than through geological processes in the earth. This organic origin contributed to their symbolism of life, purity, and innocence. In ancient Rome, pearls were highly coveted and associated with the goddess Venus, who was believed to have been born in June, cementing the pearl's connection to the month. For centuries, pearls have been symbols of wisdom gained through experience, signifying the strength developed through life’s challenges. They were often worn by royalty and nobility as ultimate symbols of wealth and status.
Moonstone shares a long history of spiritual and cultural significance. Its name is derived from its visual similarity to the moon's glow, and it has been deeply tied to lunar deities and feminine energy across various traditions. Historically, it was believed to harness the power of the moon and was often used in jewelry to promote emotional balance and intuition. Its ethereal appearance led to associations with the divine feminine, making it a favored stone for those seeking serenity and a deeper connection to their inner selves.
Alexandrite is a much more recent addition to the gemological world, discovered in the early 20th century in the Ural Mountains of Russia. Its discovery is often attributed to Imperial Russia, where it was named after the future Tsar Alexander II. The stone's unique color-changing ability—shifting from green to red—was seen as a symbol of the duality of Russian national colors, leading to its immense popularity within the country at the time. Its rarity and striking optical phenomenon quickly established it as a gem of great prestige. As a modern birthstone, added to official lists in the mid-20th century, alexandrite represents transformation and duality, appealing to those born under the sign of Gemini. The inclusion of alexandrite alongside the ancient pearl and moonstone reflects the evolution of birthstone lists to encompass gems of significant historical and scientific interest.
Geological Formation and Mining Locations
Understanding the origins of June's birthstones requires looking at two very different formation processes: organic and geological.
Pearls are unique in the gemstone kingdom as they are created by living mollusks, such as oysters and mussels. The process begins when an irritant, often a microscopic parasite or a piece of shell, becomes lodged inside the mollusk's soft tissue. To protect itself, the mollusk secretes layers of nacre, a crystalline substance composed of calcium carbonate and conchiolin, around the irritant. Over several years, these layers build up to form a pearl. Natural pearls are extremely rare and are now mostly found in antique jewelry. The vast majority of pearls on the market today are cultured pearls, which are farmed in controlled environments by intentionally introducing an irritant into the mollusk. Major sources for cultured pearls include Japan, China, and the South Sea islands.
In contrast, moonstone and alexandrite are silicate minerals formed deep within the Earth's crust under specific geological conditions. Moonstone is a variety of the mineral feldspar, specifically orthoclase or sanidine. Its characteristic sheen, known as adularescence, is caused by the intergrowth of two different feldspar species (orthoclase and albite) in microscopic layers. When light enters these layers, it is scattered, creating the stone's signature floating glow. High-quality moonstone is primarily sourced from India and Sri Lanka, with other deposits found in Brazil and the United States.
Alexandrite is a variety of the mineral chrysoberyl. Its formation requires the rare presence of chromium, which replaces some of the aluminum in the crystal structure. The chromium is what gives the stone its green color in daylight, while the presence of iron and titanium can influence its red hue in incandescent light. The specific conditions required for chromium-rich chrysoberyl are so rare that alexandrite is considered one of the scarcest gemstones. While the original and most famous deposits were in Russia's Ural Mountains, these are now largely depleted. Modern sources include Sri Lanka, Brazil, and parts of East Africa and India, though stones with the dramatic color change of the original Russian material are exceptionally rare.
Gemological Properties
The three June birthstones possess vastly different physical and optical characteristics, which influence their use in jewelry and their care requirements.
Pearl: * Composition: Organic (Calcium Carbonate - Aragonite or Calcite). * Hardness (Mohs Scale): 2.5 to 4.5. Pearls are relatively soft and susceptible to scratching. * Luster: This is the most important quality factor, referring to the amount and quality of light reflected from the surface. * Color: White, cream, pink, silver, and black. * Crystal System: N/A (amorphous).
Moonstone: * Composition: Potassium Aluminum Silicate (Feldspar). * Hardness (Mohs Scale): 6 to 6.5. * Luster: Vitreous (glass-like) to pearly on the cleavage surface. * Key Feature: Adularescence (the billowy, floating light effect). * Crystal System: Monoclinic. * Care: It has perfect cleavage in one direction, meaning it can break if struck with force.
Alexandrite: * Composition: Beryllium Aluminum Oxide (Chrysoberyl) with Chromium impurities. * Hardness (Mohs Scale): 8.5. * Luster: Vitreous (glass-like). * Key Feature: Strong pleochroism and dramatic color change from green in daylight or fluorescent light to red or purplish-red in incandescent light. * Crystal System: Orthorhombic. * Rarity: Considered one of the rarest and most valuable gemstones, especially in larger sizes with a distinct color change.

Symbolism and Metaphysical Beliefs
Throughout history, each of the June birthstones has been attributed with specific symbolic meanings and metaphysical properties, often linked to their appearance and origin.
Pearls are universally recognized as symbols of purity, innocence, and wisdom. Their formation inside a living creature lends them a unique connection to life and emotional healing. In metaphysical traditions, pearls are believed to bring inner peace, calmness, and clarity to the wearer. They are often associated with balancing one's karma and strengthening personal integrity. For those seeking to soothe emotional turmoil and foster a sense of serenity, pearls are considered a powerful ally.
Moonstone is deeply connected to lunar energy, intuition, and the divine feminine. It is widely regarded as a stone of new beginnings, inner growth, and strength. Its shimmering glow is thought to soothe the emotional body and enhance psychic abilities. Metaphysical practitioners often use moonstone to promote emotional balance, calm overactive minds, and encourage lucid dreaming. It is a stone of hope and emotional harmony, believed to align with the natural cycles of life and foster a sense of tranquility.
Alexandrite, with its dramatic color change, is a powerful symbol of duality, transformation, and joy. It embodies the concept of "the stone of yesterday and today," reflecting the ability to adapt and embrace change. In Russian lore, it was believed to bring good fortune and prosperity to its wearer. Modern crystal healing practices associate alexandrite with stimulating creativity, boosting intuition, and encouraging personal growth. It is often recommended for individuals navigating major life transitions, as it is thought to reinforce the idea that change can lead to positive outcomes.
Care and Cleaning
Due to their differing hardness and structural properties, the three June birthstones require distinct care regimens to maintain their beauty and integrity.
Pearl Care: Because of their low hardness and organic nature, pearls are delicate. They are highly susceptible to damage from acids, perfumes, hairsprays, and cosmetics, which can dull their luster and erode their nacre. It is recommended to put on pearl jewelry last when dressing and to wipe it with a soft, damp cloth after each wear. They should never be cleaned with ultrasonic cleaners or harsh chemicals. Warm, soapy water and a soft brush can be used for gentle cleaning, but they must be dried immediately and stored separately from other jewelry to avoid scratches.
Moonstone Care: Moonstone is moderately durable but has perfect cleavage, making it vulnerable to hard knocks and sudden temperature changes. It should not be subjected to rough handling or impact. Cleaning can be done with warm, soapy water and a soft brush. Avoid steam cleaning and ultrasonic cleaners, as the vibrations and heat could potentially damage the stone. Store moonstone jewelry in a soft cloth or padded box to protect it from scratches by harder gems.
Alexandrite Care: Alexandrite is quite durable, with a hardness of 8.5 and good toughness, making it suitable for all types of jewelry, including rings and bracelets that are worn daily. It is relatively easy to care for. Warm, soapy water and a soft brush are the best methods for cleaning. Ultrasonic and steam cleaning are generally safe for untreated alexandrite, but caution should be exercised if the stone has fractures that have been filled with oil or resin (a rare treatment for lower-quality stones).
