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.

Rhenium is the fourth most dense metal (weighing 21.02 g/cm3 compared with osmium at 22.59 g/cm3, iridium at 22.56 g/cm3, platinum at 21.45 g/cm3, gold at 19.30 g/cm3 and silver at 10.49 g/cm3). Rhenium also has the highest boiling point of any element at 10,170 degrees F, has the second highest melting point of any elemental metal at 5767 degrees, and also has a very high Moh's hardness of 7.0. These compare favorably with gold (melting point 1948 degrees F and Moh's harness 2.5), platinum (3215 degrees F and 3.5), iridium (4435 degrees F and 6.5). Our rhenium rings are about as durable a ring as you'll find anywhere. They are also essentially pure, unlike conventional rings in which the precious metal is alloyed, often with other nonprecious metals, to make them more durable.
 
Rhenium was discovered in Germany in 1925, was the last stable element to be discovered, and is named after the Rhine River. It is among the most rare elements in the earths crust with an estimated concentration of 1 part per billion. In 2012 only 52 tonnes of rhenium was mined worldwide compared to 2700 tonnes of gold. So, if you are interested in an elemental metal that is beautiful, rare, and elusive and will richly reflect the most striking characteristics of your soulmate, one that is among the hardest and most refractory and corrosion resistant metals in the universe, and certainly one capable of representing a pure love for eternity, then this may just be the perfect ring for you!
 

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.
