Pearl – June Birthstone
Pearls are organic gems that grow inside the tissue of a living saltwater or freshwater mollusk (either an oyster or a mussel). Natural pearls form when the mollusk secretes a substance called nacre around an irritant such as a piece of sand or a parasite that has invaded its shell. Cultured pearls are a product of human intervention. Technicians implant a piece of mantle tissue alone (common for freshwater cultured pearls) or with a mother-of-pearl shell bead (all saltwater) into a host mollusk. The mollusk covers the irritant with nacre, just like a natural pearl. Cultured pearls are raised in pearl farms – saltwater or freshwater operations where the mollusks are cleaned, protected from predators and eventually harvested. Thousands of years of pearl fishing have decimated the natural pearl beds, so cultured pearls account for the vast majority of pearl sales today. These cultured pearl birthstones come in a dazzling array of sizes, colors and shapes.
Pearls have long been associated with purity, humility and innocence. So it may be said that the June birthstone meaning is “sweet simplicity.” As such, pearls were traditionally given as a wedding gift.
Saltwater cultured pearls are grown in many areas around the world. Akoya cultured pearl farms are primarily found in Japan and China, especially along the southern coasts of Guangdong and Guangxi provinces. South Sea cultured pearls are farmed from the northern coast of Australia through Indonesia to the southern coast of Southeast Asia, with large operations in the Philippines as well. The Gambier Islands and the Tuamotu Archipelago, both part of French Polynesia, are two locales where the rich black Tahitian pearls are cultured. China is the dominant source of freshwater cultured pearls.
