June boasts a unique distinction among the birthstones – not one, but three gemstones represent the month: pearl, moonstone, and alexandrite. Each possesses a distinct allure and history, offering a diverse range of options for those seeking a meaningful and beautiful gemstone. This article will explore the origins, properties, symbolism, and significance of these three June birthstones, drawing upon available knowledge to provide a comprehensive overview.
History and Lore
For centuries, gemstones have been imbued with symbolic meaning and believed to possess healing properties. Birthstones, in particular, were thought to offer good fortune and prosperity to those born in their corresponding month. The tradition of associating specific gemstones with months dates back to ancient times, though the specific assignments have evolved over the years.
Pearls hold the longest-standing association with June, treasured for their beauty and perceived purity for millennia. Ancient cultures valued pearls not only for adornment but also for their medicinal properties. Moonstone, similarly, has a rich history steeped in mythology, linked to lunar deities in both Roman and Greek traditions, and believed to embody the power of the moon. Hindu mythology even suggests moonstones are solidified moonbeams. The use of moonstone in fine jewelry flourished during the Art Nouveau era (1890-1910), favored by designers like René Lalique and Louis Comfort Tiffany. It experienced a resurgence in popularity during the 1960s and 1990s with the “flower child” movement and New Age designers.
Alexandrite, while a more recent addition to the June birthstone family, quickly gained recognition for its remarkable color-changing ability. Its discovery in the Ural Mountains of Russia in the 19th century coincided with the Russian Czars’ colors – red and green – further enhancing its prestige.
Geological Formation and Sources
Pearls are unique among gemstones as they are formed within living organisms – mollusks. Both saltwater and freshwater pearls are valued, with South Sea pearls and Tahitian pearls being particularly prized for their size, luster, and color. South Sea pearls are harvested from a remote location in the South Seas, producing large pearls ranging in color from white to honey gold. Tahitian pearls, known for their rich black hues, are cultured in French Polynesia, specifically on Tahiti Island.
Moonstone belongs to the feldspar mineral group and is formed in igneous and metamorphic rocks. The characteristic adularescence – the shimmering, billowy light seen within the stone – is a key feature.
Alexandrite’s formation requires a unique combination of elements, including beryllium, chromium, and aluminum. The most significant sources of alexandrite historically were the Ural Mountains of Russia, though today, it is also found in Brazil, Sri Lanka, and East Africa. The intensity of the color change is a crucial factor in determining its value, with more complete shifts in hue commanding higher prices.
Gemological Properties
Pearls are not typically evaluated using the “4Cs” (cut, clarity, color, carat) in the same way as diamonds. Instead, pearl quality is assessed based on luster, nacre, surface perfection, shape, and size. Pearls are composed of calcium carbonate in minute crystalline form, which has been deposited in concentric layers.
Moonstone’s properties vary depending on its composition. It typically exhibits a hardness of 6-6.5 on the Mohs scale. The most desirable moonstones display a blue sheen against a colorless background, a phenomenon known as adularescence.
Alexandrite is a variety of the mineral chrysoberyl. It exhibits a remarkable color change depending on the light source – appearing green in daylight and red in incandescent light. It has a hardness of 8.5 on the Mohs scale, making it a durable gemstone. The more distinct the color change, the more valuable the stone.
Here's a table summarizing the key properties:
| Gemstone | Chemical Composition | Hardness (Mohs) | Key Property | Sources |
|---|---|---|---|---|
| Pearl | Calcium Carbonate | 2.5 - 4.5 | Luster, Nacre | South Seas, Tahiti, Freshwater |
| Moonstone | Feldspar | 6 - 6.5 | Adularescence (shimmering effect) | Various |
| Alexandrite | Beryllium Aluminum Oxide | 8.5 | Color Change (green to red) | Russia, Brazil, Sri Lanka, East Africa |
Symbolism and Metaphysical Beliefs
Throughout history, each of these June birthstones has been associated with specific meanings and beliefs. Pearls have long symbolized purity, innocence, and wisdom. They are often given as gifts to mark life’s significant moments, such as birthdays, graduations, and anniversaries.
Moonstone is believed to represent feminine energy, emotional balance, and intuition. It is thought to bring good luck, love, passion, and fertility.
Alexandrite, with its dynamic color change, is often associated with good fortune and balance. It is considered a stone of transformation and is believed to enhance intuition and creativity.
Generally, June birthstones are thought to represent success, happiness, and love.
Care and Cleaning
Pearls are relatively soft and require gentle care. They should be cleaned with a soft cloth and mild soap and water. Avoid harsh chemicals, ultrasonic cleaners, and abrasive materials. Pearls should also be stored separately from other jewelry to prevent scratching.
Moonstone is also susceptible to scratching and should be handled with care. It can be cleaned with a soft cloth and mild soap and water. Avoid prolonged exposure to sunlight, as it can cause the color to fade.
Alexandrite is a durable gemstone but should still be protected from harsh impacts. It can be cleaned with warm soapy water and a soft brush. Avoid ultrasonic cleaners, as they may damage the stone.
