This pendant looks like a candle of hope to me, with its brilliant colors and an aqua round "flame." The chain runs through the tube separating the two glass pieces, giving an elegant simplicity to the design. All silver is Argentium Sterling.
Argentium is a premium Sterling with a higher silver content and is silver tarnish resistant, hypo allergenic and brighter than Sterling.
Pendants come with 18” satin cord with sterling clasp. A sterling silver adjustable snake chain is available for $20 (adjustable to up to 20") or $30 (adjustable up to 30" and can slip over the head).
