Pearls were used heavily in the last 100 years. Almost all portraits of wealthy ladies showed pearl necklaces. Pearls continue to be farmed since they are still being sought, not only for jewellery but for various uses, including for women's beauty aids (supplements). Pearl dust, pearl water, and anything pearl, becomes a woman's supplementary medicine today.
Pearls are much sought after and pearl farmers need to churn as much pearls in the shortest time. How do they do that? They use technology for growing pearl oysters.
How dangerous is pearl farming to the environment? It depends on what pearl farmers put into the water to feed the pearl oysters.
Pearls come in many sizes, shapes and colours - milk white pearls, golden pearls and black pearls. I have not seen any blue pearls, emerald pearls, purple pearls and red pearls. How do we make them the colours we want? We invent new technology.
How safe is new technology in the water around us? It depends what we put into the water and what the new technology does to the environment. Cleaning the environment is what we often forget to do. We tend to go for a good harvest, so we get good money, but we forget to clean up the environment after we make a mess.
Pearl oysters grow in warm waters. Most pearl farms are in a belt at the equator and tropics. Fish constantly eat off the pearl oysters and keep them clean.
