Throughout civilizations, pearls have adorned a rich history and have often been described as a symbol of purity and innocence. Often seen as being a national treasure, pearls have even been used as currency and have always been identified as a coveted jewel. In the past, pearls were reserved for the nobility, but today they are given to celebrate birthdays, anniversaries, weddings, and many other special occasions.
The different colours of pearls also had different meanings. Golden pearls symbolized riches; white, idealism; black, philosophy; pink, beauty; red, health and energy; grey, thought; and dull pearls brought bad luck.
Before the development of pearl culture processes in 1920, divers would harvest pearls entirely by hand. In 1920, the Japanese developed a culture process which essentially put an end to pearl diving, and in turn rendered pearls more affordable for the general population. These days, virtually all pearls sold on the market are cultured; however, the techniques used to cultivate pearls have changed very little.
Pearl cultivation remains a long a tedious process often lasting several years. For example, the success rate for an Akoya pearl is approximately 20%, with only 5-10% of those being high quality. During the cultivation process, cultivators do their utmost to provide the ideal conditions for pearl growth and the well-being of the molluscs. Cultivation takes place in both fresh and salt water.
Unlike other precious stones, pearls are entirely organic. Pearls are composed of thousands of concentric layers of thin Calcium Carbonate crystals called nacre. The thickness of the nacre affects a pearl’s colour, lustre, and durability. Generally, thicker nacre equates to better pearl beauty and quality. The size of a cultured pearl is determined by the size of the oyster producing it, the size of the nucleus used, the oyster’s growing environment, and the pearl’s growth period.
There are several varieties of cultured pearls, the most common being:
