June is uniquely blessed with not one, but three recognized birthstones: Alexandrite, Pearl, and Moonstone. These gems, each possessing distinct qualities and histories, reflect the multifaceted nature of the month itself – a time associated with excitement, balance, rejuvenation, and, traditionally, marriage. While Pearl held prominence as the sole June birthstone for many years, Alexandrite and Moonstone have joined its ranks, offering a wider range of choices for those seeking a meaningful connection to their birth month. This article will delve into the history, geological origins, gemological properties, and cultural significance of each of these captivating gemstones.
A Shifting Lineup: The History of June Birthstones
The designation of birthstones has evolved over time. Initially, different cultures and eras assigned various gems to each month. The formalized modern birthstone lists began to take shape in the 19th century. In 1870, Tiffany & Co. published a pamphlet featuring “Gregorian Birthstone Poems,” attributing Pearl to June. This remained the standard for decades.
The National Association of Jewellers (now Jewellers of America) further solidified this in 1912, listing Pearl as the primary June birthstone with Moonstone as an alternative. This listing was echoed in the 1937 UK list from the National Association of Goldsmiths. However, the landscape shifted again in the 1950s when the Jewelry Industry Council of America added Alexandrite to the June birthstone family. This addition was, in part, influenced by a belief that Alexandrite was more readily available than Pearl, a notion that has since proven inaccurate.
Alexandrite: The Color-Changing Wonder
Discovered in 1834 in Russia’s Ural Mountains, Alexandrite quickly gained recognition for its remarkable optical property: its ability to change color depending on the light source. Named in honor of the future Czar Alexander II, whose birthday fell near the time of its discovery, the gem exhibits a green to bluish-green hue under normal daylight or fluorescent light, transforming into a deep red to purplish hue under incandescent light. This phenomenon, known as pleochroism, makes Alexandrite a truly exceptional and highly prized gemstone.
The initial discovery site in the Ural Mountains eventually became depleted, leading to concerns about the gem’s extinction. Fortunately, subsequent discoveries in Brazil, Sri Lanka, and Zimbabwe ensured a continued, though still limited, supply. Russian Alexandrite, however, remains particularly esteemed, historically symbolizing prestige and even mirroring the colors of the Russian military. It was reported that Alexander II himself wore an Alexandrite ring as a talisman.
Pearls: Ancient Treasures from the Sea
Pearls, unlike most gemstones formed within the earth, originate within living mollusks. The process begins when an irritant, such as a grain of sand, enters the mollusk’s shell. As a defense mechanism, the mollusk secretes layers of nacre – a substance composed of calcium carbonate – around the irritant. Over time, these concentric layers of nacre build up, creating the lustrous gem we know as a pearl.
Historically, pearls were highly valued, with the oldest written records dating back to 2206 BC in China, where they were gifted to royalty. Archaeological finds, such as the “Susa Pearls” necklace dating to 420 BC, and evidence from the Indus Valley and Sri Lanka, demonstrate the long-standing fascination with these “gems of the sea.”
Today, most pearls are cultured, meaning the irritant is intentionally inserted into the mollusk on pearl farms. Natural pearls, formed without human intervention, are rarer and typically smaller and more irregularly shaped. Common pearl types include Akoya, known for their high quality and round shape, and Freshwater pearls, which often exhibit a wider range of colors and more irregular forms.
Moonstone: The Gem of Lunar Magic
While information on Moonstone is limited within the provided sources, it is recognized as one of the three official June birthstones. Its association with the month stems from the historical connection of June to Juno, the Roman goddess of marriage, and the Latin word lunius, meaning “youth,” which evokes the moon.

Symbolism and Cultural Significance
Each of the June birthstones carries its own unique symbolism. Alexandrite, with its dynamic color change, is often likened to the complexities of love, adapting and revealing different facets. Pearls have long been associated with purity, innocence, and wisdom, and were often used in ancient civilizations as symbols of status and wealth. While the sources do not detail specific symbolism for Moonstone, its name and association with the moon suggest connections to intuition, dreams, and feminine energy.
In some cultures, Alexandrite’s color changes were interpreted as warnings of impending danger. Pearls held significant religious and mythological importance in various ancient civilizations, appearing in art and literature as symbols of beauty and grace.
Care and Cleaning
The care required for each June birthstone varies based on its properties. Pearls, being relatively soft, require gentle handling and should be cleaned with a soft cloth and mild soap. Avoid harsh chemicals and ultrasonic cleaners. Alexandrite, being a durable gemstone, can be cleaned with warm soapy water and a soft brush. However, due to its potential for color change, it’s best to avoid prolonged exposure to strong light sources during cleaning. Specific care instructions for Moonstone are not provided in the sources.
