Natural pearls grow in wild oysters. The process starts when an irritant, such as a grain of sand or a piece of shell, gets inside an oyster's shell. To protect its delicate body from the irritant, the pearl secretes a substance called nacre to surround the irritant. The oyster never stops secreting nacre, so over the years the nacre layers build up into a genuine pearl. While natural and cultured pearls are extremely similar, you can tell the difference between them with the right equipment. The key difference between natural and cultured pearls lies in the nacre layer. A natural pearl's nacre layer is much thicker than that of a cultured pearl, even when the two have a similar diameter. Natural pearls are less transparent than cultured pearls. If you place a natural pearl against a dark background - like a box lined in black cloth - and put it under a strong light, the natural pearl will look like a small, white, homogenous ball with no discernible inner rings. When you do the same to a cultured pearl, you will see a thin brown line between the nacre layer and the nucleus of the pearl. Natural pearls are extremely rare. In nature, only about one in 10,000 oysters will produce a pearl. Of those, only a small percentage will achieve the size, shape, and color of a desirable gemstone. The odds of finding a perfect natural pearl are around one in a million. Because of their rarity, natural pearls are hardly ever found in most pearl jewelry stores. Most pearls for sale in the market today have been cultured.
Recently, there has been a ton of debate as to the importance of pearl. More specifically, in regard to the passage, the writer puts forth the idea that natural pearl is very rare and demanding things and very discernible from the cultural pearl. In the listening passage, the lecturer is quick to point out there are some serious flaws in the writer’s claims. In fact, the professor believes cultural pearls are almost the same as natural pearls and addresses, in detail, the trouble with each point made in the reading text.
First and foremost, the author of the reading states that natural pearl is different from cultural pearl in many ways. Some professionals in the same field, however, stand in firm opposition to this claim. In the listening, for example, the professor states cultural pearls are almost the same as natural pearls. He goes on to say that cultural pearls hardly can differ from natural pearls.
Secondly, one group of scholars, represented by the writer, thinks that natural pearls are very precious and very rare. Only about one in 10,000 oysters produce a perfect natural pearl and the quality of a natural pearl is very high. Of course, though, not all experts in this sector believe this is accurate. Again, the speaker specifically addresses this point when he states the quality of a cultural pearl is also very good. Additionally, he notes that now the cultural pearls are mostly used as ornaments as they cannot be differentiated from natural pearls.
Finally, the author wraps his argument by positing that the making of natural pearl needs at least ten years. Not surprisingly, the lecturer takes issue with this claim by contending that for making a cultural pearl only two years is enough.
To sum up, both the writer and professor hold conflicting views about the pearl. It is clear that they will have trouble, in case of finding common ground on this issue.
