The blue glass jewel is beautifully set in a textured Argentium Sterling silver in a thick bezel bordered with a square wire border that ends in a "raindrop". A tube bail across the top carries the chain.
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).
