Shatterproof, hypoallergenic and bio-compatible, Forge has utilized Tantalum to create the most wearable contemporary metal wedding bands on the market. Because it cuts so easily, Tantalum is also one of the safest metals to remove in an emergency. Characterized by a richly saturated blue-grey color, Benchmark's Tantalum wedding rings are as elegant and luxurious as their gold and platinum counterparts. Tantalum by Benchmark is a member of the Responsible Jewelry Council (RJC) which means that they adhere to strict regulations for sustainability and ethical production. As a member of the RJC, Benchmark agrees to be randomly audited to assure that they are following the guideline of the RJC.
