The goal is to provide a comprehensive overview that is both informative and engaging for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
The Origins of June Birthstones
The tradition of birthstones dates back to ancient times, with some historians tracing its roots to the 12 tribes of Israel and the breastplate of Aaron. According to historical accounts, each of the 12 gemstones on the priest’s breastplate represented one of the tribes. Over time, the tradition evolved into associating each gemstone with a specific month of the year.
June's trio of birthstones—alexandrite, moonstone, and pearl—each has a unique historical journey.
Alexandrite
Alexandrite is the most modern of the three June birthstones. It was discovered in the Ural Mountains of Russia in 1834, coincidentally on the day that future Russian Czar Alexander II came of age. This serendipitous event led to the gemstone being named in honor of the young prince. The discovery of alexandrite marked a significant moment in gemology due to its extraordinary color-changing property, a feature that quickly made it a symbol of rarity and luxury.
Initially, alexandrite was found exclusively in the Ural Mountains, but as these deposits became depleted, new sources were discovered in Sri Lanka, East Africa, and Brazil. The alexandrite mined in Brazil, in particular, is noted for its vivid color change and has become a significant source for collectors and jewelers alike.
Moonstone
Moonstone is one of the oldest known gemstones and has been treasured for centuries. The Romans, for example, believed that its shimmering light was caused by moonlight trapped within the stone. This belief is supported by the writings of the Roman historian Pliny the Elder, who noted that moonstone's appearance seemed to shift with the phases of the moon.
The name "moonstone" is derived from this association with the moon and its ethereal glow. The gemstone is particularly popular in Indian and Eastern jewelry, where it is often used in traditional and ceremonial pieces. In ancient times, moonstone was also considered a stone of love and was believed to promote harmony in relationships.
Pearl
Pearls have an even longer history than moonstone, with evidence of their use dating back to ancient civilizations. Pearls were found in archaeological sites in Mesopotamia, Egypt, and China, where they were valued not only for their beauty but also for their rarity. In ancient Egypt, pearls were considered symbols of wealth and were often used in royal jewelry and burial adornments.
In China, pearls have long been associated with longevity, purity, and wisdom. The Chinese believed that wearing pearls could bring good fortune and protect the wearer from illness. In the West, pearls became particularly popular during the Renaissance, when they were favored by European royalty for their understated elegance and timeless appeal.
Geological Formation and Sources
Alexandrite
Alexandrite is a rare variety of the mineral chrysoberyl, which also includes other gem varieties such as cat’s-eye. What sets alexandrite apart is its unique color-changing property, which is caused by the presence of chromium within its crystal structure. This property is known as pleochroism, a phenomenon where a gemstone exhibits different colors when viewed from different angles or under different light sources.
Alexandrite typically appears green or greenish-blue in daylight and changes to a deep red or purplish hue under incandescent light. The most dramatic and desirable color change occurs in alexandrite from the original Ural deposits in Russia, where the chromatic shift is particularly vivid. However, alexandrite is now also found in Brazil, Sri Lanka, and East Africa, where it displays slightly different color variations.
The rarity of alexandrite is due in part to the specific geological conditions required for its formation. It is found in granite rock formations and is typically extracted from pegmatites, which are igneous rocks that form from the slow cooling of magma. The process of forming alexandrite requires a precise balance of temperature, pressure, and chemical composition, making it one of the rarest gemstones in the world.
Moonstone
Moonstone is a type of feldspar, a mineral group that includes many of the most common minerals in the Earth’s crust. The gemstone’s characteristic adularescence—the soft, glowing light that appears to move across its surface—is caused by the layering of different feldspar minerals within the stone. These layers scatter light in a way that creates a luminescent effect, often described as a "moonlight" glow.
Moonstone is typically white or gray in color, with a pale blue or pink sheen, although other colors such as orange and green are occasionally found. The most prized moonstone is known as "Rainbow Moonstone", which displays a multicolored sheen due to a different mineral composition. This type of moonstone is more commonly found in Sri Lanka.
Moonstone is mined in several countries, including India, Sri Lanka, Brazil, and the United States. India and Sri Lanka are particularly known for producing high-quality moonstone used in fine jewelry. The gemstone is often cut in a cabochon style to enhance its adularescence and to showcase the internal layering that gives it its distinctive glow.
Pearl
Unlike alexandrite and moonstone, pearls are organic gemstones, meaning they are formed through biological processes rather than geological ones. Pearls are created inside the mantle tissue of mollusks, such as oysters and mussels, as a defense mechanism against irritants.
When an irritant, such as a grain of sand, enters the mollusk’s shell, the mollusk responds by secreting layers of nacre (a combination of calcium carbonate and conchiolin) around the irritant. Over time, these layers form a spherical, lustrous pearl. The quality of the pearl depends on factors such as the type of mollusk, the water environment, and the time it takes to form.
Natural pearls are extremely rare, which is why cultured pearls—pearls formed with human intervention—are now more commonly available. Cultured pearls are created by introducing a small bead or piece of mantle tissue into the mollusk, which then coats it with nacre. This process mimics the natural formation of pearls and results in a similar product.
Pearls are found in both saltwater and freshwater environments. Saltwater pearls are typically produced by oysters, especially in Japan, Australia, and the Persian Gulf, while freshwater pearls are produced by mussels in rivers and lakes, particularly in China and the United States.
Saltwater pearls, such as Akoya, Tahitian, and South Sea pearls, are known for their high luster and smooth surfaces, while freshwater pearls tend to be more varied in shape and color. Pearls can range in color from white and cream to black, pink, and even green, depending on the type of mollusk and the environment in which they were formed.
