Rhenium (Re) 24 karat ring
Rhenium ring -- 24 karat (99.99% pure)
Wedding bands have traditionally been made of gold with 14 karat (or 58.5% pure) being the most common and 18 karat (or 75% pure) also available. Gold is too soft to make a durable ring out of at 24 karat purity (99.9% pure and up). There are many other alternatives to gold which have become popular including silver, platinum, palladium, tungsten, cobalt and stainless steel. Last year we released our 24 karat iridium rings and while we can't say they went viral, the response has been overwhelmingly positive so we thought we'd try another rare precious metal. Rhenium is an incredibly hard, durable and corrosion resistant metal and thus can also be issued in 24 karat purity and will last and remain beautiful indefinitely.
For now we'll take custom orders and will need between 3 and 4 months to complete this ring. If there is enough interest as there has been for our iridium rings, we'll go with a full batch to stock our standard sizes 8 through 12 at half size intervals. Each ring will be shipped with an assay certificate, our custom ring box and with our velvet logo bag. Due to the incredible properties that make rhenium such an ideal ring material, they unfortunately cannot be re-sized. 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. Domestic shipping is free for this product (just enter code free shipping at checkout). International shipping is via USPS international priority express or DHL 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.
