Bismuth metal ingot - one troy ounce - .9999 bullion
Some of bismuth's many unusual properties have been known since ancient times when it was thought to be a precursor of silver that the Earth wasn't quite finished making yet.  It has a low melting point of 521 degrees Fahrenheit, is a dense metal, it expands upon freezing as only a few other metals do, has semiconductor properties, is generally considered to be among the most diamagnetic metals and has the highest Hall coefficient.  Its well known hopper crystal form (see attached picture -- not the form we sell) has an unusual cuboidal, stairstep lattice structure with diverse iridescent hues and is really quite beautiful.  Bismuth also has diverse industrial uses including in the pharmaceutical industry, metallurgy, electronics, atomic research, and as a nontoxic alternative to lead in many applications. Bismuth is rare in the Earth's crust (see below link to our favorite chart detailing where our metals fall in terms of rarity), being about twice as prevalent as gold.  It is also considered an economically important metal with potential for supply chain risk as most of the world's supply comes from China. It therefore is near the top of the British Geologic Survey's Risk list (see below link).
Inscribed on our ingots are the chemical symbol (Bi), purity (99.99%), 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, but the grainy crystallization pattern is still visible (as are subtle iridescent hues) similar to the one pictured. There can be edge dings and other tiny imperfections which do not detract from the inherent value of this metal. As always, weight and purity are guaranteed by Rare World Metals Mint. Bismuth in the solid form we supply is considered safe. 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 an assay certificate and every shipment will include our velvet logo bag. 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.
