A thick emerald green was broken into a triangle by the Atlantic and turbulently tumbled by waves until perfectly frosted.  I found it on a NY beach, drilled it, and adorned it with a fine silver bail textured with mandalas.  Sterling silver was melted at one end so that it formed a small ball, and was strung through the sea glass and bail to allow subtle movement.  The pendant is approximately 1 1/4 inches long and hangs from a 19-inch leather cord.
