MADE & SHIPS FROM USA
Perfect gift for that special someone even if that is you.  Artisan cultured sea glass 30mm focal bead, artistic non-tarnish wire-wrapped heart with round sea glass bead dangle & hung on a plated ~18" chain. We do have 14kg sterling silver chains available in other listings if you prefer.  This photo is enlarged to show detail.

Cultured sea glass (some call beach glass) has been physically & chemically weathered which produces natural frosted glass giving these the same effect as pieces of sea glass you find along the ocean shores - but you get a bigger color range, & more uniform shape, with the cultured sea glass.

There are plenty of free online measurement converters.
