How about a personalized pendant for someone special in your life, or maybe for yourself? I can stamp almost anything you like. Disc is 3/4 inch (18mm). Aluminum is a great alternative to sterling, it looks and feels very similar without the price tag!!
**Add a sterling 1mm box chain ($10), or a silver plated cable chain ($5) in lengths 20", 18", 16", 14". Add crystal birthstones of the grand kids ($1.50 each). See last photo for how they would look.
