An O-ring is a round ring that is used as a gasket for sealing a connection. O-rings are typically constructed out of polyurethane, silicone, neoprene, nitrile rubber or fluorocarbon. These rings are commonly used in mechanical applications, such as pipe connections, and help to ensure a tight seal between two objects.
Platinum is also used in rings at almost 100% purity. It is a dense metal, so a platinum ring will feel heavier on the hand than other options. Because of its higher cost, platinum is most often used in men's and women's wedding and engagement rings and less frequently in fashion or cocktail rings.
