Pearl vs Jeddah

Informations

A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold.

Imitation pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor and is easily distinguished from that of genuine pearls. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past were also used to adorn clothing. They have also been crushed and used in cosmetics, medicines and paint formulations. Whether wild or cultured, gem-quality pearls are almost always nacreous and iridescent, like the interior of the shell that produces them. However, almost all species of shelled mollusks are capable of producing pearls (technically "calcareous concretions") of lesser shine or less spherical shape. Although these may also be legitimately referred to as "pearls" by gemological labs and also under U.S. Federal Trade Commission rules, and are formed in the same way, most of them have no value except as curiosities.

Jeddah is the principal gateway to Mecca, the holiest city in Islam, located just 65 kilometres (40 mi) to the east, while Medina, the second-holiest city, is located 360 kilometres (220 mi) to the north. Economically, Jeddah is focusing on further developing capital investment in scientific and engineering leadership within Saudi Arabia, and the Middle East.

Jeddah was independently ranked fourth in the Africa – Mid-East region in terms of innovation in 2009 in the Innovation Cities Index.Jeddah is of Saudi Arabia's primary resort cities and was named a Beta world city by the Globalization and World Cities Study Group and Network (GaWC). Given the city's close proximity to the Red Sea, fishing and seafood dominates the food culture unlike other parts of the country. In Arabic, the city's motto is "Jeddah Ghair", which translates to "Jeddah is different". The motto has been widely used among both locals as well as foreign visitors. The city had been previously perceived as the "most open" city in Saudi Arabia.
