How do I find a Webb site/store for the Sands of Time castle sculptures-made in Canada, trademarked? Thanks!?

These are tiny, solid, sculptures made of ? with the exterior of white sand and sparkles and usually containing a crystal. I need 2 for kids who just lost their father in a plane crash - idea, his birthstone and his castle in heaven. I received one in the early 1990's as a gift. Don't know where it was purchased?
