Iridium metal ingot - one troy ounce - .9995 bullion
Iridium was discovered by Smithson Tennant in 1803 and named after the Greek goddess Iris due to the brilliant colors of its salts. A member of the platinum group metals, iridium is the most corrosion resistant metal, is the second most dense and has the second highest modulus of elasticity (edged out by osmium for both of these properties) and has a very high melting point. It is one of the rarest elements in the Earth's crust with an estimated concentration of 0.001 parts per million (gold is about 40 times more abundant). It is estimated that 3 tonnes of iridium is produced worldwide annually (compared with about 2500 tonnes of gold). It is used in the electronics, aerospace and chemical industries.
Inscribed on our ingots are the chemical symbol (Ir), purity (99.95%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These ingots are lightly polished, similar to the one pictured. There can be tiny edge dings and other tiny imperfections which do not detract from the inherent value of this rare precious metal. As always, weight and purity are guaranteed by Rare World Metals Mint. Iridium is not known to be toxic and the solid form we supply is considered safe. Its fine turnings or powder form could ignite in air and can be an irritant to eyes and mucous membranes. As we suggest with all of our metals please keep in a safe place, do not ingest, and keep out of the reach of children.
Each ingot will be shipped with a laminated assay certificate and with our velvet logo bag for storage. If you are not completely satisfied with any purchase from us, you have 30 days to return it for a full refund (buyer to pay return shipping). Domestic shipping is free for all orders over $99 (enter code free shipping at checkout). For orders of $99 or under, domestic shipping is $9.95. International shipping is via DHL, FedEx, or USPS international express and costs $45 for shipments up to a pound (9 one ounce ingots or less including packaging materials) and $10 for each additional pound. International customers please be aware that your country may levy import duties and/or VAT taxes on your purchase from us. We have nothing to do with this and cannot pay it for you. If you refuse our package because of this extra cost we will take it back and will refund your order in full once received minus the cost of the return shipping. If you are unsure what these import costs will be please check with your country's customs office.
