1. IELTS Reading Passage: The Pearl

Below is the original text and the set of questions. Try to complete the exercises before checking the explanations provided below.

The Pearl

A. The pearl has always held a special status among the rich and powerful throughout history. For instance, women from ancient Rome went to bed wearing pearls so they could remind themselves of their wealth upon waking. Pearls used to have more commercial value than diamonds until jewelers learned how to cut gems. In eastern countries like Persia, ground pearl powder was used as a medicine to cure various ailments, including heart disease and epilepsy.

B. Pearls can generally be divided into three categories: natural, cultured, and imitation. When an irritant (such as a grain of sand) enters a certain type of oyster, mussel, or clam, the mollusc secretes a fluid as a defense mechanism to coat the irritant. Gradually, layers accumulate around the irritant until a lustrous natural pearl is formed.

C. A cultured pearl undergoes the same process. There is only one difference between cultured and natural pearls: in cultured pearls, the irritant is a bead called “mother of pearl” that is placed inside the oyster through surgical implantation. This results in much larger cores in cultivated pearls than those in natural ones. As long as there are enough layers of nacre (the secreted fluid covering the irritant) to create a gorgeous, gem-quality pearl, the size of the nucleus does not affect its beauty or durability.

D. Pearls can come from both saltwater and freshwater sources. Typically, saltwater pearls are of higher quality, although several freshwater pearls are also considered high-quality. In addition, freshwater pearls often have irregular shapes, with a “puffed rice” appearance. Nevertheless, it is the individual merits that determine a pearl’s value more than its source. Saltwater pearl oysters are usually cultivated in protected lagoons or volcanic atolls, while most freshwater cultured pearls sold today come from China. There are a number of options for producing cultured pearls: using freshwater or seawater shells, transplanting the graft into the mantle or the gonad, and adding a spherical bead or producing them non-beaded.

E. Regardless of the method used, the process usually takes several years. Mussels must reach a mature age, which may take up to nearly three years, before being transplanted as an irritant. Once the irritant is in place, it takes approximately another three years for a pearl to reach its full size. Sometimes, the irritant may be rejected. As a result, the pearl may be seriously deformed, or the oyster may die from various complications, such as disease. At the end of a 5- to 10-year cycle, only half of the oysters may survive. Among the pearls that are actually produced, only about 5% will be of high enough quality for jewelry makers.

F. Imitation pearls are a different story. The Island of Mallorca in Spain is renowned for its imitation pearl industry. In most cases, a bead is dipped into a solution made from fish scales. But this coating is quite thin and often wears off. One way to distinguish imitation pearls is to bite them. Fake pearls glide through your teeth, while the layers of nacre on real pearls feel gritty.

G. Several factors are taken into account to evaluate a pearl: size, shape, color, surface quality, and luster. Generally, the three types of pearls are ranked in the following order of decreasing value: natural pearls, cultured pearls, and imitation pearls (which are basically worthless). For jewelers, one way to determine whether a pearl is natural or cultured is to send it to a gem lab and perform an X-ray. High-quality natural pearls are extremely rare. Japan’s Akoya pearls are among the glossiest, while the “South Sea” waters of Australia are a cradle for larger pearls.

H. Historically, the highest-quality pearls in the world were found in the Persian Gulf, particularly around Bahrain. These pearls had to be hand-harvested by divers without advanced equipment. Unfortunately, when large oil reserves were discovered in the early 1930s, the Persian Gulf’s natural pearl industry came to a sudden end because the contaminated water destroyed the once-pristine pearls. Today, India likely holds the largest stock of natural pearls. However, it is ironic that a large portion of India’s stock of natural pearls originally came from Bahrain.

Questions

Summary of the Reading Passage

The passage provides a comprehensive overview of pearls through several aspects:

• History & Value (Paragraph A): Pearls were once symbols of wealth (Ancient Rome) and used as medicine (Persia). Before gem-cutting techniques were developed, pearls were more valuable than diamonds.

• Classification & Formation (Paragraphs B, C): There are 3 types: natural, cultured, and imitation. Pearls form when an irritant enters an oyster/mussel, stimulating it to secrete nacre to coat the object. The main difference: cultured pearls are created by humans inserting a bead (nucleus) via surgery.

• Origins (Paragraph D): Pearls can come from saltwater (usually higher quality) or freshwater (often from China, with irregular shapes).

• Cultivation difficulties (Paragraph E): The process takes many years (5-10 years) and carries high risks (oyster death, pearl deformation). Only 5% of finished pearls reach jewelry-grade quality.

• Imitation pearls (Paragraph F): Mallorca (Spain) is famous for imitation pearls made from fish scales. A way to distinguish them is to bite them: fake pearls feel smooth/slippery, while real pearls feel gritty.

• Evaluation & Geography (Paragraphs G, H): Evaluation criteria include size, shape, color, and luster. Japan is famous for its glossy pearls (Akoya), while Australia produces larger ones. The Persian Gulf (Bahrain) was once the source of the best pearls but declined due to oil exploration.
