Chrysocolla chalcedony is the most well-known gemstone variety in Taiwan. Because of its beautiful green-blue to blue-green color, chrysocolla chalcedony is also known as ＂Taiwan Blue Chalcedony＂ by the jewellery industry. Chrysocolla chalcedony from different mines in the world is mostly produced in the form of porphyry copper deposit, which is formed by hydrothermal process and is mainly composed of cryptocrystalline silica and a series of copper-containing minerals such as chrysocolla. The beautiful color of chrysocolla chalcedony is caused by chrysocolla inclusions. ＂Taiwan blue chalcedony＂ is mainly produced in the andesite and volcanic breccia of the Dulan Shan Formation of the Coastal Range, especially in the fissures or rupture zones of the celadonitized host rock as a lens due to metasomatism. Regulated by Mineral Industries Act, Taiwanese local mines are strictly restrained with increasing environmental cost for mining and the limited production capacity, which result in the high value of ＂Taiwan blue chalcedony＂. With the increasing market demand for ＂Taiwan Blue Chalcedony＂, imported chrysocolla chalcedony has been sold in the trade name of ＂Taiwan Blue Chalcedony＂ and impacted local chrysocolla chalcedony severely. In response to the needs of the jewellery industry, this study conducts a series of mineralogical and geochemical analyses on chrysocolla chalcedony from seven origins: Bao-Feng-Xiang Mine Pit 1, Dulan Mountain Range, Taiwan; Inspiration Mine, Arizona, USA; Ray Mine, Arizona, USA; Lily, Pisco, Peru; Arequipa, Peru; Kasiruta Island, Indonesia; Zecatecas, Mexico. The motivation for this study is to distinguish the origin of chrysocolla chalcedony by mineral composition and geochemical characteristics, as feasibility evaluation on the origin identification of chrysocolla chalcedony from Taiwan and other countries in the future. Preliminary results show that the chrysocolla chalcedony of different origins may be distinguished by the content of moganite. Chrysocolla chalcedony from Indonesia has the highest average moganite content; Chrysocolla chalcedony from Zecatecas Mine in Mexico has the lowest average moganite content which is close to zero content. Chrysocolla chalcedony of some origin has significant differences in geochemical characteristics: for instance, compared with other origins, chrysocolla chalcedony from Bao-Feng-Xiang Mine has a trend of higher manganese, higher uranium and higher potassium content.
