Ruthenium belongs to the platinum group metals (PGMs) and is exceedingly rare. Worldwide annual production is estimated between 12 and 20 tonnes of ruthenium compared to 3000+ tonnes of gold. It is corrosion and wear resistant and its alloys can be superconductive. It has other unusual and unique properties and has applications in electronics, chemical and solar power industries.

Our first batch of 24 karat, 99.9% pure ruthenium rings have been cast in various sizes between US sizes 4.75 and 12.75. The inner circumference of our rings are inscribed in a small font with RWMM XXXX - Ru .999 , reflecting our brand, the element symbol, purity (99.9+%) and XXXX is a four digit serial number which is unique for each ring. These rings cannot be re-sized, but as with our other products we will allow up to 30 days for returns in case it doesn't fit or you don't love it for any reason.
Each ring will be shipped with an assay certificate, our custom ring box and with 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 this ring. 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.
