Winds, Waves, and Wonders: Is There Room for Pearls in a Changing World?

(This post is part of our blog series that deals with Pearls International’s take on social and environmental responsibility. For more information on how Pearls International gives back, please click here.)

While the pearl as a gem is one of the oldest jewels known to man, the pearl industry in its currently recognizable form came about only in the last century with the advent of improved pearl culturing methods that made it possible to produce these lovely trinkets on a scale fit for the masses.

While the sudden glut of inexpensive cultured pearls sent the centuries-old natural pearl market into a tailspin, a new buyer appeared. The solidly middle-class families of post-WWII America, newly solvent and looking to make their mark on the world of fashion by keeping up with the Joneses, were at once fascinated by the exotic provenance and mystery of the pearls they saw adorning the necks of Hollywood’s darlings, and charmed by the clever marketing schemes of sellers determined to convince them of the value of gems previously considered counterfeits. Not only did this glamorous gem catch the eye of Americans, the pearl industry began to boom all over the world. Growing economies made for perfect consumers, and today, pearls make up a significant portion of the jewelry market worldwide. In fact, Australia is the leading country in pearl production. In Western Australia alone, the total allowable annual catch of oysters per licensed pearl production company is 572,000 oysters, equaling over $200 million dollars’ worth of pearls!

Post-War, business was booming, but not without repercussions to ancient oyster beds, which were rapidly depleted by the sudden demand. Oyster species that ordinarily took several years to mature were now being forced to produce pearls faster and more frequently, leading oyster farmers to breed stock with shells so weak they were flexible to the touch. Due to pollution, over farming, industrialization, and other factors from man made activities, water quality in many marine oyster environments was slipping. These animals are very sensitive, and productivity dropped drastically. Many pearl farmers in coastal China were forced to take their business to cleaner waters in other countries. From this turmoil, the Chinese freshwater pearl business began to grow and become more prominent.

Initially, cultured pearls from China were created from the irritant being implanted into the animal at one year of age. Eventually, in order to increase quality, they made a few changes, including switching the species of mollusk used and waiting until they were two and a half, rather than one year old. These freshwater mussels are raised in former rice paddies that have been flooded to create lakes for pearl farming. They enrich these lakes with manure to increase algae growth, on which the mussels feed. They also add filter-feeding carp to the environment to filter out phytoplankton and prevent algal blooms. This increases the quality of the food source for the mussels. The aim is to raise healthy animals so that they can continue to produce quality gems. However, sometimes the artificially created ecosystem does not function as well as was intended. A few years ago, mussel farming was banned in one province of China due to concerns from questionable levels of manure content in the paddies. While the mussels do benefit from the steps taken to build their habitat, it must be monitored and the water must be kept clean. Just as the lakes the mussels are raised in are affected by outside sources such as pollution, construction, and waste, the surrounding ecosystems are effected by the pearl farms. One pearl farmer was quoted as saying “We must keep a Confucian balance with nature.”

Chinese pearl farmers may use as many as 10 irritants per mollusk, where many other countries (particularly when producing saltwater pearls) only use 1-2 irritants. In fact, by 2015, it is predicted that China will surpass Australia as the leader in pearl production worldwide. Because they can turn out so many pearls, they sell them at a much lower cost. This has raised fears among other countries that the pearl industry as a whole may become endangered. Chinese workers in pearl farms make a low wage of $15 – $23 a day. Looking to reduce costs even further, some Chinese companies are developing pearl-sorting machines rather than having them chosen and placed with similar pearls by hand. These machines take pictures of the pearl from every angle as it drops, then catches the gem and evaluates it based on size, luster and imperfections. It automatically assigns the pearl to a bin in which it will be kept with similar pearls. As these machines can run day and night and work quickly, they will be able to replace around 15 human workers per machine. This hurts the job market for individuals working in pearl production, and could have drastic effects on the Chinese economy.

You could imagine that with such a constantly growing, worldwide industry, there are a lot of people on our planet who are affected by pearl production. Let’s look at French Polynesia, a small group of islands that makes a good bit of its livelihood from pearl farming. Much of their revenue comes from international exports, and 55% of their exports in 2008 were black Tahitian pearls. An estimated 4,000 persons in French Polynesia live from pearl farming, with much of this industry being made up of family-owned businesses.

This booming industry has led to a decrease in emigration from the Gambier and Tuamotu archipelagos to Tahiti, which is what many young people had to do in order to find work previously. Consequently, both the populations of these small islands and the quality of living have increased sufficiently to allow many people to remain living on the islands of their birth. Social and health benefits have arisen from this as well, as many inhabitants of the region enjoy the kind of outdoor physical work provided from pearl farming, as it provides a way of life close to the traditional activities of the population.

On the flip side, not all family-owned pearl farming operations are successful. Many families who try to get into the business without knowledge of entrepreneurship go bankrupt when they are unable to pay back their small business loans. Socially, this creates inequalities among the population, as on some islands the pearl business is booming and on some it is nearly impossible to produce pearls. Some families who are successfully producing pearls are producing low quality jewels and marketing them poorly, leading to many big producers pushing for more regulations on pearl farming in the islands. Also, many local families of the smaller islands face competition from non-locals who have taken over pearl farming on the main island of Tahiti. In addition to local competition, the value of the Tahitian pearl market is being challenged by pearl production companies worldwide, particularly from Chinese freshwater pearls. As Chinese pearls are more cheaply produced, they sell for a much, much lower wholesale cost than saltwater Tahitian pearls. The majority of the buying market would rather buy freshwater pearls at a third of the cost of a similar Tahitian strand.

Although the competition may be tough, the pearl industry on the French Polynesian islands is still a major point of production on a global scale. In the words of Laurent Cartier, an environmental science Ph.D. who did some work on a research paper on sustainability of pearls, “In the long run, only those producers who work in ecologically responsible ways will continue to produce top-quality pearls.” Cartier believes that the methods used by Chinese pearl farmers can over crowd the mollusks, and ultimately thinks that saltwater pearl farming tends to use more environmentally conscious methods. Kamoka Pearl, one French Polynesian family-owned pearl farm, tells National Geographic about their efforts to remain environmentally conscious in an article published this year. The oysters are kept loosely packed into nets within the lagoon that they are harvested from, in order to be watched over and kept track of by pearl farmers.

A problem that oyster farmers face by keeping them this way is that they then begin to grow barnacles and other organisms on their shells. In order to keep the oyster growing at a normal and healthy rate, and therefore producing high quality pearls, these growths must be cleaned. There are several ways to effectively clean an oyster. The most common method is bringing the nets out of the water and spraying them with a high pressure hose. This is inexpensive and effective, but creates a large amount of organic matter in the water. This decreases the water quality, because it becomes to much for the fish and other marine animals to break down efficiently. Kamoka Pearl, however, has found an environmentally conscious way around this problem. Rather than hosing the oysters off, they move them to shallow areas of the lagoon where fish life is more abundant and varied. After a few days, the fish clean the oysters naturally. Although this isn’t as quick or cheap in means of labor costs, the company prefers to spend the extra money to do what they feel is best for the environment.

Whether or not pearl farming is beneficial or detrimental to the environment depends on the methods used to farm the mollusks and environmental factors from other industries. Research is still underway. New knowledge, methods of farming, and innovations in technology are being discovered day-to-day. The question of whether there is room for pearls in a changing world can safely be assumed as a yes, as long as we leave enough room for the ocean to continue its natural processes. We have seen since the invention of cultured pearls all the way to today that with changes in society, come changes in the pearl industry, and these changes can have varied and lasting effects. It appears that the pearl industry has set itself up to be as timeless as the gems themselves are.

Gemstone Spotlight: The Pearl! June’s Treasure

“Who comes with summer to this earth
And owes to June her hour of birth
A pearl should wear against her skin
Who’s innocence many a heart shall win.”

– Gregorian Birthstone Poem

Could you guess which month is our favorite? The birthstone for June is the pearl! Other accepted stones are alexandrite and moonstone, but when you can claim pearls as your gem why would you want another option?! We at Pearls International are always excited for a chance to talk about pearls. June girls are lucky to have such a unique gem to call their own. Pearls are so special because they are the only gem that is produced by a living organism. They are perfect from the moment they leave the shell, requiring no polishing, faceting, or other enhancements, and you will never find two pearls that are perfectly identical. If you are a fan of our site, you’ll know they come in a huge variety of colors, shapes, and sizes! Pearls are found all over the world, with most freshwater pearls coming from China and Japan. Many saltwater pearls are also found in Japan, and are commonly farmed in the Tahitian islands and Australia as well.

The history and mythology of the pearl is another part of what makes them so unique, special, and interesting. Almost all pearls today are cultured, which means an irritant has been placed into a mollusk by a human and the pearl has formed around that irritant. This process was developed around the 1920s. Before cultured pearls, the only pearl jewelry was made from pearls found in an oyster by chance. Only about one in 10,000 oysters will produce a gem quality pearl by itself, so as you can imagine, a strand of natural pearls would have been very, very expensive back then. In fact, did you know a strand of pearls once paid for an entire house? It sounds too crazy to be true, but it is. Pearls really are legendary. Legends around their origins formed from a variety of cultures around the world. The Chinese believed the gem to have formed inside the brains of dragons, while other cultures thought they were formed when oysters swallowed drops of moonlight. The Greeks thought they were drops of water flung from Aphrodite’s body when she was born from the sea.
