History and Lore
The history of June’s birthstones is as varied as the stones themselves, with each carrying deep cultural and historical significance.
Pearls have been treasured for millennia, with their use in adornment dating back to ancient civilizations. They are the only gems created by living organisms, formed within the soft tissue of mollusks. Historically, pearls were symbols of purity, wisdom, and wealth. In many cultures, they were associated with the moon and were believed to offer protection and attract good luck. White pearls, in particular, have long been a universal symbol of purity and innocence, making them a timeless choice for bridal jewelry and classic gifts. The association of pearls with inner peace, wisdom, and prosperity is a belief that has persisted through the ages, reinforcing their status as a gem of profound meaning. The classic white Akoya Pearl is often considered the quintessential June birthstone, representing timeless elegance and purity.
Moonstone has a history steeped in mysticism and folklore. Its name derives from its ethereal sheen, which resembles the glow of the moon. For centuries, moonstone has been associated with feminine energy, intuition, and inner clarity. It was believed to embody the power of the moon and was often worn as a talisman for protection, love, and good fortune. In many traditions, moonstone was thought to enhance psychic abilities and promote emotional balance. The stone’s soft, milky hues and its captivating play of light, often shifting from light blue to pink depending on the angle, have made it a favorite for jewelry that evokes a sense of mystery and elegance. Its symbolism of embracing the feminine and achieving inner clarity continues to resonate with wearers today.
Alexandrite is a relatively modern gemstone with a dramatic history. Discovered in the Ural Mountains of Russia in the 1830s, it was named after the future Tsar Alexander II. Its most remarkable characteristic is its color change: it appears green in daylight and fluorescent light, and transitions to a reddish or purplish hue under incandescent light. This phenomenon was seen as a powerful omen, and the stone became a symbol of duality and balance, often associated with the national colors of Imperial Russia. The discovery of alexandrite was particularly significant as it provided a gemstone that could be worn in place of emeralds during the day and rubies by night. Its rarity and unique color-changing property have made it one of the most coveted and valuable of all gemstones, symbolizing a bold and sophisticated aesthetic.
Geological Formation and Sources
Understanding the formation and origin of these birthstones provides insight into their rarity and value.
Pearls are organic gems formed within the mantle of certain species of mollusks, including oysters and mussels. The process begins when an irritant, such as a grain of sand or a microscopic parasite, becomes lodged in the mollusk’s soft tissue. To protect itself, the mollusk secretes layers of nacre (a combination of aragonite and conchiolin) around the irritant, eventually forming a pearl. Natural pearls are exceptionally rare, as they occur without human intervention. Most pearls on the market today are cultured, where a technician intentionally introduces an irritant to stimulate nacre production. Pearls are harvested in saltwater and freshwater environments across the globe. Notable sources include the Akoya pearls from Japan and China, South Sea pearls from Australia, Indonesia, and the Philippines, and Tahitian pearls from French Polynesia. Freshwater pearls are primarily cultivated in China. Each type of pearl possesses unique characteristics in terms of size, luster, and overtone.
Moonstone is a variety of the mineral feldspar, specifically orthoclase or sanidine. It forms in igneous and metamorphic rocks. The gem’s signature sheen, known as adularescence, is caused by the intergrowth of two different feldspar minerals (orthoclase and albite) in microscopic, alternating layers. When light enters the stone, it scatters between these layers, creating the characteristic soft, floating light effect. The finest moonstones are found in Sri Lanka and India. Other sources include Myanmar (Burma), Madagascar, and the United States (notably in Virginia and North Carolina). The quality of moonstone is judged by its color, clarity, and the strength of its adularescence. The most prized specimens exhibit a clear, blue sheen against a colorless or milky white body.
Alexandrite is a chrysoberyl, one of the rarest gem minerals. It forms under specific geological conditions where beryllium and chromium are present together, typically in pegmatites and metamorphic rocks. The color change is due to the presence of chromium, which absorbs light in the yellow and blue parts of the spectrum, allowing green and red to dominate under different light sources. The original and most famous source was the Ural Mountains of Russia, but these deposits are now largely depleted. Today, significant sources include Sri Lanka, Brazil (Minas Gerais), Tanzania, and India. The quality of alexandrite is determined by the strength and clarity of its color change, with the most valuable stones showing a distinct shift from vibrant green to rich red. The size of the stone also impacts its value, as faceted alexandrite over one carat is exceedingly rare.
Gemological Properties
The physical and chemical properties of each birthstone dictate its durability, appearance, and care requirements.
Pearls are unique among gemstones as they are organic. Their hardness is relatively low on the Mohs scale, typically ranging from 2.5 to 4.5, depending on the nacre quality. They are not rated on the standard 10-point Mohs scale due to their organic composition. The primary gemological properties are luster, surface quality, shape, size, and color. Luster, which refers to the quality of light reflected from the surface, is a critical indicator of a pearl’s value. High-quality pearls exhibit a sharp, bright reflection. The chemical composition is primarily calcium carbonate (CaCO3) in the form of aragonite crystals, bound by conchiolin. Pearls are susceptible to damage from acids, chemicals, and abrasion, making careful handling essential.
Moonstone is a member of the feldspar group, with a chemical formula of KAlSi₃O₈ (for orthoclase). It has a Mohs hardness of 6 to 6.5, making it moderately durable but susceptible to scratching by harder materials. It has perfect cleavage in two directions, which means it can split easily if struck with force, requiring careful setting and handling. Its refractive index ranges from 1.518 to 1.526, and it exhibits a trichroic pleochroism (showing three different colors when viewed from different angles). The most desirable feature is its adularescence, a soft, billowy sheen that moves across the stone’s surface. Moonstone is typically cut into cabochons to best display this optical effect.
Alexandrite is a chrysoberyl with a chemical composition of BeAl₂O₄ and contains trace amounts of chromium (Cr³⁺), which is responsible for its color change. It is a very hard and durable gemstone, with a Mohs hardness of 8.5, making it suitable for all types of jewelry, including rings. It has a refractive index of 1.746 to 1.755 and a specific gravity of 3.73. Its most defining gemological property is its trichroism and color change. Under daylight or fluorescent light, it appears green to bluish-green; under incandescent light, it shifts to red or purplish-red. The quality of this color change is a primary factor in determining its value. Alexandrite is typically faceted to enhance its brilliance and color play.
Summary of Key Gemological Properties

Care and Cleaning
Proper care is essential to maintain the beauty and longevity of these birthstones, with each requiring specific handling due to their unique properties.
Pearls are the most delicate of the three and require careful attention. Due to their low hardness and porous nature, they are vulnerable to scratches, acids, and chemicals. It is recommended to put on pearl jewelry after applying cosmetics, perfumes, and hairsprays, as these can damage the nacre. Cleaning should be done with a soft, damp cloth after each wear to remove body oils and dirt. Avoid ultrasonic cleaners, steamers, and harsh chemicals, as these can strip the nacre or damage the pearl’s surface. Store pearls separately from other jewelry to prevent scratches, preferably in a soft pouch or lined box.
Moonstone, with a Mohs hardness of 6 to 6.5, is moderately durable but has perfect cleavage, making it susceptible to breaking if struck. It should be protected from hard blows and extreme temperature changes. Cleaning moonstone is relatively straightforward: use warm water, a mild soap, and a soft brush. Rinse thoroughly and dry with a soft cloth. Avoid ultrasonic cleaners and harsh chemicals, which could damage the stone or its setting. It is best to remove moonstone jewelry during activities that could subject it to impact.
Alexandrite is the most durable of the three, with a Mohs hardness of 8.5. It is resistant to scratches and can withstand daily wear, making it an excellent choice for rings and other high-impact jewelry. However, like all gemstones, it can still be damaged by sharp blows. Cleaning is simple: use warm soapy water, a soft brush, and rinse well. Ultrasonic cleaners are generally safe for alexandrite, but it is always advisable to check with a professional jeweler if the stone is set in a delicate or old mounting. As with all fine jewelry, it is wise to remove alexandrite pieces during strenuous activities to prevent accidental damage.
