Pearl vs Galle

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.

Galle (Sinhala: ගාල්ල, romanized: Gālla; Tamil: காலி, romanized: Kāli) (formerly Point de Galle) is a major city in Sri Lanka, situated on the southwestern tip, 119 km from Colombo. Galle is the provincial capital and largest city of Southern Province, Sri Lanka and is the capital of Galle District. Galle was known as Gimhathiththa(although Ibn Batuta a Moroccan Arab Muslim traveler in the 14th century refers to it as Qali) before the arrival of the Portuguese in the 16th century, when it was the main port on the island. Galle reached the height of its development in the 18th century, during the Dutch colonial period. Galle is the best example of a fortified city built by the Portuguese in South and Southeast Asia, showing the interaction between Portuguese architectural styles and native traditions. The city was extensively fortified by the Dutch during the 17th century from 1649 onwards. The Galle fort is a world heritage site and is the largest remaining fortress in Asia built by European occupiers. Other prominent landmarks in Galle include the city's natural harbour, the National Maritime Museum, St.

Mary's Cathedral founded by Jesuit priests, one of the main Shiva temples on the island, and Amangalla, the historic luxury hotel. On 26 December 2004, the city was devastated by the massive tsunami caused by the 2004 Indian Ocean earthquake, which occurred off the coast of Indonesia a thousand miles away. Thousands were killed in the city alone. Galle is home to the Galle International Stadium, which is considered to be one of the most picturesque cricket grounds in the world. The ground, which was severely damaged by the tsunami, was rebuilt and test matches resumed there on 18 December 2007. Important natural geographical features in Galle include Rumassala in Unawatuna, a large mound-like hill that forms the eastern protective barrier to Galle Harbour. Local tradition associates this hill with some events of Ramayana, one of the great Hindu epics. The major river in the area is the Gin River (Gin Ganga), which begins from Gongala Kanda, passes villages such as Neluwa, Nagoda, Baddegama, Thelikada and Wakwella, and reaches the sea at Ginthota. The river is bridged at Wakwella by the Wakwella Bridge.
