No beach glass or pebbles for me!  Polymer clay rocks secured to metal adjustable rings. Knuckle rings are in and the bigger they are...

A Blue Sharpie, a smooth, plastic ornament and some basic shapes make for a pretty ornament. As seen on Pinterest, wipe the ornament with some rubbing alcohol, use a pattern or make one up, take your marker and start drawing.  I sealed mine with PYMII.   The mirrored balls are on a timer.  I mixed 2 strings of battery operated lighted mirrored balls in with the ornaments.  The glass vase and crystal pillar candle holder are from Goodwill.  I'm so happy with this arrangement.  It's also my nightlight. I love how soft the lighting is.  I'm going to hate to take it down.
