In September 2009 Americans Elements announced the creation of the first pure Iridium Jewelry filing a patent on the invention. Since their launch Iridium wedding rings have been acquired by people as diverse as a well-known L.A. artist and an important London banker (all of whom shall remain anonymous). Iridium is the lowest tarnishing metal in the universe and will thus hold its unique silver-gray luster longer and under more extreme conditions than even gold, silver and platinum making it the perfect expression of eternal love.

Why might you ask has it taken so long for Iridium jewelry to be created? The answer lies in the high technology properties of Iridium. For example, gold melts at 1,945° F, well within the working range of jewelers. Iridium melts at a staggering 4,435° F, far outside the range a jeweler can work with. Due to this and other elemental properties of the metal, making jewelry from Iridium is extremely difficult and in fact falls within the purview of materials scientists and engineers. As materials scientists, American Elements maintains longstanding expertise producing high tech forms of Iridium for scientific, research and space applications. Now, working with NY and LA based jewelry designers, we have created and patented a pure Iridium ring or wedding band as well as other jewelry settings, bracelets and watchbands of the highest quality. Wholesale arrangements are also available to jewelry manufacturers, retailers and shopping networks.

Rings can be custom manufactured to any established ring size. See a U.S. and European ring chart for standard sizes. AE wedding rings are an innovative and unique statement and are available in palladium and palladium. Custom configurations are also available. Iridium will virtually never change color or oxidize having the highest resistance to corrosion. Being much rarer and more difficult to produce than even platinum (it has a melting point 500° F above even platinum), an iridium wedding ring is an extremely unique and luxurious choice. AE also produce Iridium as rod , pellets , powder , pieces , granules , ingot , wire , and in compound forms, such as oxide.

Iridium (Ir) atomic and molecular weight, atomic number and elemental symbolIridium (atomic symbol: Ir, atomic number: 77) is a Block D, Group 9, Period 6 element with an atomic weight of 192.217. The number of electrons in each of iridium's shells is [2, 8, 18, 32, 15, 2] and its electron configuration is [Xe] 4f14 5d7 6s2.Iridium Bohr ModelThe iridium atom has a radius of 136 pm and a Van der Waals radius of 202 pm. Iridium was discovered and first isolated by Smithson Tennant in 1803. In its elemental form, Iridium has a silvery white appearance. Iridium is a member of the platinum group of metals. It is the most corrosion resistant metal known and is the second-densest element (after osmium).Elemental Iridium It will not react with any acid and can only be attacked by certain molten salts, such as molten sodium chloride. Iridium is found as an uncombined element and in iridium-osmium alloys. Iridium's name is derived from the Greek goddess Iris, personification of the rainbow, on account of the striking and diverse colors of its salts.
