Osmium metal ingot - one troy ounce - .9995 bullion - platinum group metal
Osmium belongs to the platinum group metals (PGMs) and is the rarest stable element in the earth's crust and is also the most dense. Its estimated average concentration in the earths crust is 0.05 parts per billion. Worldwide annual production is only 1 or 2 tonnes of osmium compared to 2700 tonnes of gold. It has unique properties that have applications in the medical and electronics industries. Please see the below links for more information. Inscribed on our ingots are the chemical symbol (Os), 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, though not all are as well polished as the single one pictured. These ingots are very hard and dense and as they are sintered, are prone to have small edge chips and shallow edge peels. They nicely demonstrate the characteristic blueish hue of osmium and are incredibly heavy for their size. Like with all of our products, these ingots were designed and manufactured with careful attention to weight and purity, both of which have been checked and rechecked throughout the manufacturing process and are guaranteed by us. The powder form of osmium can be dangerous given the high toxicity of its oxidized state, osmium tetroxide, and the greater surface area of powder for oxidation to occur. The solid ingot form that we sell is relatively safe. Please refer to the safety information that will come with your shipment, use appropriate handling precautions and store your osmium in a safe place away from children who might try to ingest it.
Each ingot will be shipped with a laminated assay certificate, a packet of safety information 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 $199 (enter code free shipping at checkout). For orders of $199 or under, domestic shipping is $9.95. International shipping is now via USPS international priority 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.
