Freshwater Vs Saltwater Pearls - What's the Difference?

Quality freshwater pearls are a fairly new stock of more developed cultivation methods. In the early 1900s and early, freshwater was seen as an inferior product. Saltwater pearls were more important since their shape was more regular, they were more lustrous, and their size was much bigger. Today, things are a minuscule different. These two types of pearls are still dissimilar from each other but the differences are much less than they used to be.

Freshwater pearls are, as the name implies, only found in freshwater mollusks. Though they may also have a perfectly round shape, just as saltwater ones, they are slightly more likely to have an irregular, baroque shape. This is due to the cultivation method, in part. Whereas saltwater cultivation methods use a small piece of shell or a bead, freshwater pearls are cultivated by implanting a small piece of mantle or other tissue. The nacre doesn't have a fully round nucleus and so is less likely to be round when harvested. Natural pearls are roughly always irregular. It is also much easier to mass produce freshwater pearls, as each oyster may be implanted many times - I've read that they can produce up to 20 pearls for each oyster though less is more likely.

Saltwater pearls are only found in the ocean or other bodies of saltwater. They are normally round, with very high luster. However, they have less nacre than their freshwater cousins, development them slightly less durable and more prone to chipping colse to the drill holes. It is also impossible to mass produce through current cultivation methods. Each oyster produces one pearl, and many do not survive to be implanted again. It is worth mentioning here that pearls can also be found from conches, on rare occasions. These tend to be pink with a "flame" pattern that makes them very valuable. Natural black pearls (versus those that are dyed black) are also only harvested from saltwater mollusks.

There are a wide range of colors ready from each, although as mentioned above black pearls and the pink conch pearls are saltwater only. Freshwater pearls have more colors ready though, as it is easier to control the outcome by adding metals to the water. Thus you will find pink, lavender, white, yellow, and many other shades.

Pearls - Natural, Cultured, Freshwater, Saltwater - What's the Difference?

Jewelry has been a popular way of decorating oneself for thousands of years. Many population choose to use jewelry as a fashion statement or as some sort of status symbol. Other population attach more meaning to a unavoidable gemstone, piece of stone, or high-priced metal. There are many reasons jewelry is foremost to so many population in so many different cultures. One type of jewelry that has been popular for a very long time is pearl jewelry. There are many different kinds of pearls, but the most often discussed varieties are natural and cultured pearls. Here are some facts that will help you understand the difference.

A pearl is a hard round object formed and produced within the flesh of many different sorts of shelled mollusks. Many different types of mollusks can yield pearls. Among them are clams, oysters, mussels, etc. A pearl is formed simply when a very small particle or other intruder, like a grain of sand, finds its way into the mollusk and settles there. The mollusk becomes annoyed and secretes a calcium carbonate called nacre that surrounds and isolates the intruder and makes it into a pearl. This secretion process is repeated many times and forms several different layers around the particle to form the pearl. The longer the particle is inside the mollusk, the larger the pearl may become. One of the features that give a pearl so much value and beauty is the luster or iridescence that is shown off by the pearl. They are also popular for their approximately exquisite white color. Other colors are also popular, such as pink pearls and black or Tahitian pearls.

Pearls

One of the key distinctions that are foremost to make when you are referring to pearls is the divergence between natural and cultured pearls. Natural pearls are pearls that are formed without the intervention of any human to yield the pearl. Natural pearls can be formed as mentioned before by a small particle like a grain of sand or other organic organism that invades the mollusks flesh, or even by a piece of flesh that has been wounded or broken off for some reason or another. Natural pearls are approximately all the time more indispensable than cultured pearls because they are much more difficult to come by. Cultured pearls and natural pearls look approximately same on the exterior because they are formed in the same way. The one thing that makes a cultured pearl different from a natural one is the proximity of human intervention.

Pearls - Natural, Cultured, Freshwater, Saltwater - What's the Difference?

People learned that a pearl could be forced to be formed if a small piece of something were located inside of the pearl producing oyster or other mollusk. This object is regularly a small bead or piece of sand and is located inside the mollusk to promote the production of a pearl. Cultured pearls have become a kind of art form and many different shapes can be made depending on the form of the traditional implant because the pearl will regularly consequent the same shape as the object that intruded.

Another divergence to be found among pearls is freshwater or saltwater. Many pearls are produced by oysters that are found in the ocean. But there are other mollusks that dwell in rivers that can also yield pearls. Freshwater pearls are also easier for man to yield because there are less variables and potential problems in a controlled fresh water environment than in the open sea. Many population assume that freshwater pearls are all the time cultured pearls but this is not true. It is foremost to understand the divergence between cultured and natural pearls and between freshwater and saltwater pearls to for real understand why they are different.

Cultured Pearls Or Natural Pearls - What's the Difference?

What is the difference between Cultured and Natural Pearls? The difference is in the introductory way the gem is provoked. Natural pearls have formed by accident, without humans being complicated in the process. Cultured pearls have grown in an oyster or mussel after humans have inserted a tiny irritant to provoke the amelioration of the pearl.

How Natural Pearls Form

Pearls

The irritant that initiated the formation of a natural pearl may have been a toady that penetrated the shell of the mollusc, disturbing the layer of mantle cells that yield the shiny interior of the shell. These dislodged mantle cells then multiply until they meet each other, forming a small pearl sac. Inside this sac the mantle cells secrete the nacre that would regularly have formed into mother-of-pearl on the inside of the shell. But within the diminutive sac that has formed, layer upon layer of nacre builds up and grows into a natural pearl.

Cultured Pearls Or Natural Pearls - What's the Difference?

How Cultured Pearls Form

Humans deliberately insert a tiny piece of mantle tissue into a mollusc to provoke the increase of a pearl sac, where a pearl will form. Freshwater pearls are formed this way. The rest of the process proceeds the same way that a natural pearl would form. Saltwater varieties of cultured pearls have a tiny bead made from the shell of another mollusc surgically inserted along with the mantle tissue to ensure the roundness of the pearl. The oyster will then strike for home to coat the bead with layer upon layer of nacre until a pearl is built up over time.

Distinguishing between Natural and Cultured Pearls

As both types of pearls are produced by the same animals with the same nacre, they can be hard to distinguish with the naked eye. Before the arrival of tissue nucleation, the nearnessy of a bead nucleus was the determining factor in distinguishing between the two. In a process similar to the old institution of candling eggs, pearls can be held over the beam of a flashlight to try to decide if they consist of a round nucleus. Alternatively, the pearls can be analyzed under ultraviolet light that will show natural ones in varying intensities of yellowish or tan color as opposed to the blueish white color displayed by cultured ones. When purchasing what you believe to be a natural pearl, it's all the time advisable to ask the jobber to furnish certification of its being natural from a dependable gemology laboratory. There trained specialists use x-ray equipment to decide the type of pearl it is. Natural ones on average tend to be smaller in size than cultured ones. Necklaces are seldom of thoroughly uniform color and perfectly matched shapes. But because of their rarity, newly found natural pearls are regularly much more costly than cultured ones.

Other Types of Natural Pearls

Not all pearls are formed in the way described above. Some are non-nacreous. Gem experts don't consider them true pearls, because they have no nacre, but they are gorgeous and extremely valued. Examples of these calcareous concretions are those produced by the Queen Conch and the Melo Melo Snail. Both yield gem ability pearls. Pink conch pearls and orange melo melo pearls have both been determined natural pearls until up-to-date breakthroughs in the culturing of the conch pearls. Up till now almost all of those ready for sale have advanced as accidents of nature and fetch a high price. They seem to be more prone to fading than nacreous ones, so should be kept out of sunlight. The most extremely valued have an curious flame structure, which gives the appearance of fine lines reminiscent of wet silk, or a cat's eyes. These pearls are very hard to find and are regularly sold as a singular pearl or pair rather than as pearl necklaces. The pink conch pearls tend to be very small in size.
