Resin keepsake- sand and stones

Sand from a special vacation turned into a keepsake! I use top-quality non yellowing resin in hand-made sterling silver settings. These can be personalized on the back with a short message or even coordinates, which has been a popular request. Can you guess where the sand and tiny stones in these are from?!
