World Federation Of Diamond Bourses
The World Federation of Diamond Bourses, founded in 1947, was created to provide bourses trading in rough and polished diamonds and precious stones with a common set of trading practices. It is composed of 30 member diamond bourses. Their headquarters are in Antwerp. Members of The World Federation of Diamond Bourses (WFDB) act as a medium for wholesale diamond exchange, trading both polished and rough diamonds. The WFDB consists of independent diamond bourses in major centers of the diamond trade such as Tel Aviv, Antwerp, Mumbai, Johannesburg, London and New York and other cities across the USA, Europe and Asia. The WFDB provides a legal framework and convenes to enact regulations for its members. The following is a list of the 30 bourses. * Antwerpsche Diamantkring CVBA (Belgium) *Bangkok Diamonds and Precious Stones Exchange (Thailand) * Beurs voor Diamanthandel CVBA (Belgium) *Bharat Diamond Bourse (India) * Borsa Diamanti D'Italia (Italy) *Borsa Istanbul (Turkey) * Diamant- ...

Diamond Chamber Of Russia
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
