Your mind probably doesn't wander to the small Indian Ocean island of Sri Lanka. This rugged yet charming island south of India is loaded with sacred cities, ancient Buddhist ruins and beaches that will impress even the most well-traveled beach bums.
I have also seen similar centerpieces that use epsom salts instead of sugar. You could also sprinkle a mix of pearls/gems. Sand (or sugar), faux pearls, a 3 candle. An easy DIY wedding centerpiece idea.
