"金銀珠寶人人愛！"……本文將討論下述各點：

  (1). 計量單位 (Units)

  (2). 珠寶及寶石 (Jewery and Precious Stones)

  (3). 鉑 (白金，Platinum)

  (4). 金 (黃金，Gold)

  (5). 銀 (Silver)

<2>.半寶石常見的有二十多種，包括：

瑪瑙 紫水晶 綠柱石（海藍寶石）  黃水晶 石榴石

橄欖石 蛋白石 尖晶石 坦尚黝簾石 虎眼石

綠松石 黃玉（黃晶）  電氣石 (碧璽) 鋯石

<3>.嚴格上不算做寶石，即不屬於礦物的有機體，但也作為珠寶的有：琥珀；煤玉；珍珠；珊瑚；象牙。

<4>.中國人在傳統上非常重視玉。玉通常分為軟玉（昆崙山是主要產地）和硬玉（翡翠，主要產於緬甸），所謂「黃金有價玉無價」；但在世界其他地區沒有將玉視為寶石。

寶石在寶石學中由以下特徵分類：

<1>.構造；例如，鑽石是完全碳；紅寶石是氧化鋁。（參見元素） 

<2>.結晶系統：例如，立方晶系、三方晶系、單斜晶系。 

<3>.晶體習性：例如，八面體結晶。 

同一種寶石有不同變化，例如：

<1>.紅寶石和不同顏色的藍寶石都是剛玉變化而來的。 

<2>.金綠玉有金綠玉貓眼石，亞歷山大變色石

Jewellery (pronounced /ˈdʒuːl(ə)ri/; also spelled jewelry, see spelling differences) is an item of personal adornment, such as a necklace, ring, brooch or bracelet, that is worn by a person. It may be made from gemstones or precious metals, but may be from any other material, and may be appreciated because of geometric or other patterns, or meaningful symbols. Earrings and other body rings are also considered to be jewellery, while body art is not. Also, items affixed to a garment, such as buttons, are not considered to be jewellery, even if they are unusual and highly decorative. Also, items such as belts and handbags etc. are not considered to be jewellery, and are considered to be accessories.

        The word jewellery is derived from the word jewel, which was anglicised from the Old French "jouel" circa the 13th century^[1] . Further tracing leads back to the Latin word "jocale", meaning plaything. Jewellery is one of the oldest forms of body adornment; recently found 100,000 year-old beads made from Nassarius shells are thought to be the oldest known jewellery^[2] .

        Jewellery is sometimes seen as wealth storage or functionally as holding a garment or hair together. It has from very early times also been regarded as a form of personal adornment. The first pieces of jewellery were made from natural materials, such as bone, animal teeth, shell, wood and carved stone. More exotic jewellery was probably made for wealthy people or as indications of social status. In some cases people were buried with their jewellery.

        Jewellery has been made to adorn nearly every body part, from hairpins to toe rings and many more types of jewellery. While high-quality jewellery is made with gemstones and precious metals, such as silver or gold, there is also a growing demand for art jewellery where design and creativity is prized above material value. In addition, there is the less costly costume jewellery, made from lower value materials and mass-produced. Other variations include wire sculpture (wrap) jewellery, using anything from base metal wire with rock tumbled stone to precious metals and precious gemstones.

[3B英文]：Platinum，http://en.wikipedia.org/wiki/Platinum

Platinum (pronounced /ˈplætɨnəm/) is a chemical element with the chemical symbol Pt and an atomic number of 78. Its name is derived from the Spanish term platina del Pinto, which is literally translated into "little silver of the Pinto River^[1]." It is in Group 10 of the periodic table of elements. A dense, malleable, ductile, precious, gray-white transition metal, platinum is resistant to corrosion and occurs in some nickel and copper ores along with some native deposits. Platinum is used in jewelry, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry, and catalytic converters. Platinum bullion has the ISO currency code of XPT. Platinum is a commodity with a value that fluctuates according to market forces. On April 2nd, 2009, Platinum was worth $1165.00 per troy ounce (approximately $37.46 per gram^[2]).
