This 18-karat yellow gold round closed ring features flat sides and is cast as a single, seamless element; there are no weak spots. Use this ring in your gold designs or pair it with oxidized silver or another color of gold. The flat sides reflect the light, while the rounded edges preserve its elegant look. Closed rings have no opening and are ideal as attach rings for clasps, as end rings on strung or wire-wrapped pendants, drop or dangle designs, or as connecting rings between fabricated or metal-formed links and components. A closed ring presents a strong, smooth finish with no joint and no need to solder.
